If we don't have this "back" dependency, then we cannot make sure,
that the unversioned dependency is installed at all. The reason for
the unversioned packages was to provide a user with the "python"
binary. If the dependency is made "python" without "(>= 2.3)", then
it's not clear which version get's installed. I think this will be a
non-issue after the transition is done.

yes, but only because the release was scheduled for the "beginning of
2003" :-) But it's certainly useful to make these kind of packages for
the alpha releases.
