We don't need to publicize that there is a possibility that we can go back in our decision.
We just said that. I think it is necessary to *force* all participating projects to switch to PHP 5 only, in all circumstances. If we just give in when nothing has changed in february 2008, we end up in the same state as we are now.
Just keep forging ahead as if PHP4 does not exist, and corner ourselves?
If all participating projects (most major ones showed interest) use PHP 5 from 2008 on, we are not cornering ourselves as Drupal's competitors are also PHP5 only.
We can say that we reevaluate this in February and that is it. We don't need to make any decisions now (apart from pushing hard for hosts and distros to go PHP5).
Again, if hosters don't have a reason (= major PHP software is PHP 5 only) to upgrade, they won't. I think it is necessary to decide *now* to give everyone half a year's notice. Konstantin Käfer – http://kkaefer.com/
