It would lead to other shows trying to argue that "well, the 4 leads of Follies pull equal weight and should be recognized as a core" or "the whole cast of this British import should be jointly recognized." I get why people are saying it for SIX, but I would be SHOCKED if it happened. This is not a Matilda situation, nor is it a special event situation like Springsteen. The Billy Elliott & Side Show situations were unique and the Tonys –– currently –– does not operate under those rules."
Respectfully, I can't say I agree with any part of this assessment.
Firstly, there's already precedent for awarding special Tonys to ensembles (the 2002 revival of La Boheme, for example).
Secondly, the Special Tony goes wherever the committee wants. There's no need to be concerned with what precedent it will set, because the committee is under no obligation to follow up-on that precedent. True, it might cause people to say "hey, they awarded Six, so why not award [so-and-so future ensemble]" and the simple answer will be "They didn't feel like it." The special Tony is designed to award excellence wherever they see it.
And yes, it's common to award work that isn't eligible in regular competition, but not necessarily. For example, they recently gave John Leguizamo a special Tony for his run of "Latin History for Morons," even though he was eligible for Best Actor and Best Play - and he even got nominated for the latter, despite also receiving the special Tony the same year! But they felt comfortable doing it because they knew, presumably, that the show was unlikely to be considered a viable winner for Best Play, despite being excellent in its own unique way.
And I think that same logic can apply here; even though the 6 actors are eligible to be nominated, the committee will certainly be aware of how difficult and unusual the situation is, especially given the point of the show. So it seems totally plausible that they'd choose to award them a special Tony.
The one disclaimer I should add is: I haven't seen this cast, so I can't actually say whether I think they DESERVE a Special Tony for their work. I'm just making a case that they fit the bill in theory.
