That said, there are syntax changes ('except...as...' being the big one) that make supporting 2.5->3 difficult, and only becomes reasonable at 2.6->3.

A shared codebase definitely isn't reasonable if you want to support
Python 2.5. At least not for a project the size of Twisted.

(why doesn't your mail / news client word wrap paragraps?)
