Well, it's the right word. If you're going to do a hardfork by changing 
the timestamp definition, you're already doing a hardfork. At that 
point, you've already crossed the Rubicon and might as well put in any 
other necessary changes (e.g. to transaction locking), because it will 
be as much of a hardfork either way.

The important bit here is "as long as it doesn't change anything now" - 
this is indeed a hardfork, but it's a timestamp-activated hardfork that 
triggers in 2106. Until that point, it has absolutely no bearing on 
consensus rules (as opposed to the other proposals, which are at least a 
soft-fork today).

I understand that there's some problems in getting consensus for forks, 
but surely we can agree that everyone will update their Bitcoin at least 
once in the next 85 years? (If they don't, they're doomed anyway.)
