You are confused. At least two people were *for* dropping 2.2 support
in this thread, and nobody was against it. I'm pretty sure several
others have been for dropping it on IRC, as well.
I have seen people several times commit code that requires 2.3,
realize that the buildbot failed, and replace the code with a more
complicated version (didn't you do this recently yourself, Jp?). I
personally find it harder and harder to test 2.2, as finding an
installation of 2.2 is getting rarer these days. To unshamedly list
features from the "What's new in Python 2.3" article:
- Proper booleans (2.2.0 didn't even have the "True" and "False" constants)
- generators without __future__
- callable types
- horrible obscure Python2.2-only bugs and semantics changes gone
- str in str
These are all pretty minor (apart from the "horrible obscure" things),
but the sum() of them adds up to a lot of annoyance in support when no
users have actually thrown in for it.
