Symfony / PHP Compatiblity… Biggest problem.

While reading this article

was surprised that php6 is so close. I must say I’m not a fan of php upgrades. I mean for me php always had enough functions / syntax and I would not ever change them (since php4) except fixing bugs. Of course this is wrong thinking b/c moving forward is probably the most important thing to give a chance for language to survive. But knowing about php6 it makes me think that the biggest issue I can think of symfony is another one symfony release (which would support php6) which wont be compatible with previous versions. I mean that we have symfony 1.0, 1.1, 1.2 and all of them are actually incompatible. So as a result we have to support (and keep in mind differences) for all 3 branches. Plus it’s not really straightforward to keep 3 working branches of symfony on the same server.

So I really wish that symfony would either support some kind of good migration tool (so the project WORK after migration operations) or keep next releases 100% compatible with 1.2 without any “but” things.
