Hi,

Thank you for starting this, it's a good exercise to do.

While some libraries may simply be feature complete, there are
definitely cases which we may consider removing.

Things like traceback2, linecache2, simplegeneric, extras and unittest2
are essentially backports of Python 3 features to Python 2 and earlier
Python 3. There is little reason for us to use them, although older
projects may bring these dependencies with them.

Things like testscenarios and testrepository are, as far as I remember,
related to the old ways we ran unit tests. I think I managed to get rid
of them on all projects I'm on without any loss.

Nose is not maintained any more apparently.

I haven't looked into the others, but these seem to be candidates for
removal.
