I just want to say what I think is the best option and why. Let's say something like 2 years in which miners can signal activation after which, the MUST signal it for their blocks to be valid (I think this is LOT=3Dtrue, but I don't remember what LOT stands for). Some may argue than it's easier to move from LOT=3Dfalse to LOT=3Dtrue than viceversa (I think I'm getting this right), but either way different clients could interpret things more differently more easily and, you know, that's really bad. If anyone is against the consensus change itself, what they should do is run a client in which the must is turned into a MUST NOT. Whenever miners signal activation, blocks aren't valid so that it doesn't happen. That way both sides can be cleanly separated and both communities (assuming there's a community of users opposing the change) can stick together with their own in the same chain. That is, having only 2 chains in total if there are users opposing the change or only one if not, but never 2 chains for people who want the change or 2 chains for pople who don't want it. Just my two sats, please nobody ask me "why would anyone oppose taproot?" or anything similar. Because I'm trying to generalize here, if we're talking about activation, I think the specifics of the change are kind of irrelevant. Separately: thanks to everyone who worked on taproot.
