Centos and Red Hat production systems still use Python 2.4, so yes, 
absolutely, 2.5 and 2.4 still need to be supported.

Not necessarily by package authors though -- that's a matter for them to 
decide. I'm presently writing a small library which will support 2.4 
through 3.2, which isn't as hard as it sounds like, but still isn't 
exactly fun. If the project were much bigger, I'd drop support for 2.4 
and only support 2.5. At least then I could use conditional expressions 
and __future__ imports.

It really depends on *your* users, not arbitrary developers. How many of 
your users are using 2.5?
