It might be more complex, but in general we really don't want to add
functionality to Emacs core that is already available on ELPA, because
we are working towards shipping the whole of GNU ELPA with our release
tarballs.  Then we would be shipping the same functionality twice.

So if vundo can already do what ediff-undo and diff-with-undo are for,
then I'm afraid we probably shouldn't continue working on the latter
two.  I hope this is not too disappointing.
