First, I'd like to know why this discussion is happening on the committers list.

Python-dev is the right list for these things. I've adjusted the CC accordingly.

I am planning to offer a single file patch for 2.3 and 2.4. As far as one more 2.5 release, I don't think there's going to be many changes to the 2.5 branch between now and 2.6/3.0 final - although if there is, we'll obviously have to do another release. I would like to establish a tradition where, after some final bug fix release (e.g. for 2.5), further "mere" bug fixes are banned from the maintenance branch (and I did revert several bug fixes from the 2.4 branch). I'm not sure I agree with this policy. Can you elaborate on /why/ you want this? Because there won't typically be sufficient testing and release infrastructure to allow arbitrary bug fixes to be committed on the branch. The buildbots are turned off, and nobody tests the release candidate, no Windows binaries are provided - thus, chances are very high that a bug fix release for some very old branch will be worse than the previous release, rather than better.

Second, I don't think this is true. People using those patch level releases will test and report bugs if they are introduced by such backports.

Besides, developers backporting such changes are diligent enough to test their changes - they will usually have a reason for applying the extra effort to backport.

I don't see any advantage in undoing already tested and committed patches to an older branch.

Note that Python 2.4 is still widely used out there. As an example, all the Zope and Plone installations run Python 2.4 and will continue to do so for quite a while.

And there's a reason for this slow uptake of Python 2.5: as more and more servers run 64-bit OSes, the Py_ssize_t changes cause serious trouble with Python C extensions that were not updated by their authors.
