VC is in dire need of improvement, indeed.  I would welcome such
a project and would be happy to mentor.

That would be good as well, but only if the tab-widget can be placed
anywhere in the window tree (e.g. per-window, per-frame, or somewhere in
between) and can be used for different purposes (e.g. switch buffers in
a window or switch window-configs in a frame, or switch branches in
a VC-dir buffer).
There are existing branches providing some kind of tabs support already,
but they didn't get much traction.

I'm not sure how useful these would be (the second point also seems
much too trivial for GSoC, it might not be much more than a two-liner).

But if you're interested on working around the text-property code,
I recommend the "using interval trees for overlays" and the
"text-property planes" suggestions already mentioned by Jambunathan.
