I personally considered unladen-swallow a fork (although they claim on their
site that it's a branch rather than a fork). Also, given the fact that
they're enhancing a version of Python (2.x) which the official guys are
trying to move people off, it was a problem.
With this announcement though (which as of now looks like vapourware), Py3k
will have performance benefits as well. That would be an extra reason to

Given the size of project, you're probably right but atleast there seems to
be a nascent plan to do that.

This is what Unladen swallow has done but with two differences
0. They branched 2.x rather than 3
1. They have completely separate repo and project site (which makes it like
IronPython or Jython rather than a branch of CPython itself).
The current announcement seems to be a unifying one and that's a good sign.
Whether it will happen is a different question.
