How do you propose avoiding divergent consensus rules on the network, something which a number of commentors on this 
list have publicly committed to?

I think this is one of the strongest arguments against a flag day activation, but, as I described in more detail in the 
thread "Straight Flag Day (Height) Taproot Activation", I'm not sure we aren't there enough already.

Could you clarify what an acceptable timeline is, then? Six months from release of new consensus rules to activation (in 
the case of a one-year original window) seems incredibly agressive for a flag-day activation, let alone one with 
forced-signaling, which would require significantly higher level of adoption to avoid network split risk. In such a 
world, we'd probably get Taproot faster with a flag day from day one.

That was precisely the original goal with the LOT=false movement - do something easy and avoid having to hash out all 
the technical details of a second deployment. Sadly, that's no longer tennable as a number of people are publicly 
committed to deploying LOT=true software on the network ASAP.
