Revising the Rules - Bringing Back 'Banned As Commander'

Lutri, the Spellchaser by Lie Setiawan
The last three years of Magic have seen over 100 bans across all formats, more than the previous ten years combined. Of that ever-growing banlist, Commander contributes just five cards. One of the pleasures of this format is how rarely we have our toys taken away from us, and how hesitant the RC has been with the banhammer. But that's not to say their approach is perfect.
Exactly seven years and one day ago, there were two distinct banlists; banned in Commander and banned as commander. Certain legendaries were deemed troublesome in the command zone but acceptable in the 99. But on the 12th of September, 2014 the banned as commander list was abolished, and with it went Braids, Cabal Minion
Why Did The RC Remove Banned As Commander (BAC)?
At the time, the RC said that having two banlists was "unnecessary information overhead" and a single list would be more streamlined. Commander players at large took this as the RC lacking faith in their ability to make sense of two banlists, at least enough for Sheldon Menery to address it earlier this year.
Sheldon stated that overwhelming complexity was not the reason for the change. He has every faith in the average Magic player's ability to understand two banlists, but feels maintaining a unified list is "crisp, clean, and straightforward to communicate". I see this as contradictory. If the average Magic player can make sense of a more nuanced banlist, surely said list can tolerate being ever so slightly less crisp and clean?
(Spoiler alert: I think there should be three banned lists, but we'll get to that.)
The Virtues of Banned As Commander
It isn't hard to see that having a banned as commander list allows for a more nuanced approach to banning in general. To look briefly at more traditional 60-card Constructed formats, take Lurrus of the Dream-Den
The same principle applies to Commander. Cards consigned to your deck are usually harder to abuse and less likely to cause problems than the ones in a special zone you always have access to. So it stands to reason a format with a unique zone should have a banlist that acknowledges the unique challenges of that zone.
Wouldn't This Lead To More Bans?
I am a player who prefers unbans to bans. But as Sheldon has warned, the reintroduction of BAC could lead to more bans rather than less, so perhaps I should be careful what I wish for. Sheldon suggests a number of legendaries would go onto the BAC list, but roughly half of them were in wide circulation before the September 12 change of 2014. If they didn't warrant inclusion then, why now?
I'm not arguing Derevi, Empyrial Tactician
Do We Need Rules For Corner Cases?
Sheldon makes clear in his reassessment of bringing back banned as commander that "you don't make format-level rules for corner cases." While this sounds reasonable, the printing of companions and their friction with Commander's lack of sideboards lead to a rewriting of rule 11 and a mention in rule 3. If not a format-level rule for a corner case, I'm not sure what else to call this change.
I'll concede that the return of banned as commander would also be a corner case, but with the amount of cards being printed every year increasing rapidly and WotC working in curiouser and curiouser spaces, I wager we'll be seeing a lot more corners. Rules for corner cases are a good thing and allow for more freedom for both deck builders and card designers.
The Hateful Eight
There are currently eight banned legendary creatures and it wouldn't be fair to advocate for this change without being upfront about my thoughts on each one.
Braids, Cabal Minion
Emrakul, the Aeons Torn
Erayo, Soratami Ascendant
Griselbrand
Iona, Shield of Emeria
Unbanning Leovold, Emissary of Trest
Lutri, the Spellchaser
Rofellos, Llanowar Emissary made a lot more sense to be on the banned in commander list back in 2014. But it's 2021, and both Kinnan, Bonder Prodigy and Selvala, Heart of the Wilds exist. They both produce more mana at a quicker rate and have inbuilt card advantage. They may require slightly more focused deckbuilding to reach their full potential but they are certainly the stronger cards. The problem with Rofellos is that a deck of just commons and bargain-bin rares can always guarantee six mana on turn three. This creates problems at lower to mid power tables. He is probably okay to unban as a commander, and definitely okay to unban in the 99. Yes, even with Yavimaya, Cradle of Growth now in print. I don't see him being much worse than Cabal Coffers.
Three Banlists Then?
I mentioned earlier that I'm in favor of having three different banlists, which is technically true. A banlist for commanders, a banlist for the 99, and a banlist for companions. You might think it silly to have a banlist for companions given that only Lutri would go on it, and you'd be right. But practically, this can all be the same banlist. The only thing needed is an asterisk next to each banned card. The conditions for a card's legality could be clarified by a simple footnote. Vintage can handle it, why can't Commander?
But as always, that's just how I see it. What matters most is your take, and how your playgroup feels about it. Whatever you think, I'd love to hear your thoughts.
