[bitcoin-dev] Yesterday's Taproot activation meeting on lockinontimeout (LOT)

This is absolutely the case, however note that the activation method itself is consensus code which executes as a part 
of a fork, and one which deserves as much scrutiny as anything else. While taproot is a model of how a soft-fork should 
be designed, this doesn't imply anything about the consensus code which represents the activation thereof.

Hence all the debate around activation - ultimately its also defining a fork, and given the politics around it, one 
which almost certainly carries significantly more risk than Taproot.

Note that I don't believe anyone is advocating for "try to activate, and if it fails, move on". Various people have 
various views on how conservative and timelines for what to do at that point, but I believe most in this discussion are 
OK with flag-day-based activation (given some level of care) if it becomes clear Taproot is supported by a vast majority 
of Bitcoin users and is only not activating due to lagging miner upgrades.
