It may not be the ideal thing, but it seems better than the alternatives. 
Getting on a release rhythm may entail some occassional irritation, but I 
do think its worth the trouble.

Having the freeze dates be something that people know from remember when 
it happened last year seems more important than exactly when we release to 
the world.  As long as there's been a release in the last year the user is 
going to feel like we're making progress, but the developers care about 
the exact freeze data because presumably they have something that they 
want in before the freeze.

Instead of "er" you could say "Release X and X+3, and X+4 are supported, 
please help us to minimize the hassle of voluntarily maintaining bugzilla 
by using one of those.  Oh, by the way, X+3 is our next long-term stable 
release, so you'll be able to get support for it for a couple years."

If people ignored the idea and went on doing what they've been doing then 
certainly practice would not exhibit the idea.
