Yes, I know what the difference between them is at a technical level. You
didn't explain why this would make any difference to how fast miners
upgrade. The amount of money they lose in both cases is identical: they are
equally incentivised to upgrade with both fork types.
Additionally, you say in a hard fork the other chain may "continue
forever". Why do you think this is not true for miners building invalid
blocks on top of the main chain? Why would that not continue forever?
There just isn't any difference between the two fork types in terms of how
fast miners would upgrade. Heck if anything, a hard fork should promote
faster upgrades, because if a miner isn't paying attention to their
debug.log they might miss the warnings. A soft fork would then look
identical to a run of really bad luck, which can legitimately happen from
time to time. A hard fork results in your node having a different height to
everyone else, which is easily detectable by just checking a block explorer.

Isn't that circular? This thread is about deployment of CLTV, but the BIP
assumes a particular mechanism, so pointing out problems with it is off
topic? Why have a thread at all?
