That's not true in my experience. 2 years ago I used those "ancient" stuff.

that's not true at all. True, you can update python itself easily, but
updating things like pygtk or pyqt are near impossible without the
support of IT staff (because you generally lacks X11 headers, or gcc
is too old).

That's not exactly true - python developers will not give security
updates, but I think RH may still do so.

People running svn are a small proportion of our userbase. And the 2.4
support cost is fairly minimal IMO. Certainly, 2.4 support is more
important than 3.x at this point.
