Why it should be kept there?
If there is nobody to do such simple clean up then expect it to grow into a big
pile of garbage that consumes bandwidth, disk space and braincycles.
Sorry, I do not possess commit privileges to keep Python developers busy with
important tasks.
There is, of course, a need for a vendor branch: it is the baseline of the code
that we run. Unfortunately, it isn't used for that, but I wouldn't want to remove
it.
If you don't need it, just don't check it out.
From that I can see the version in vendor branch doesn't match the version of
the tracker instances used.
If there is a reason for that branch to stay, I would like to know it, because I
would like to hack/test some features for python.org and if there are any
limitations it is better to know about them beforehand.
