Yeah, this is kind of what I was thinking with the
'project-additional-buffers' idea.  This could be implementation
agnostic as well, and be just a flat list connected to some root,
persisted in the project list.  As such, this will always be consulted
when invoking "project-find-files", "project-switch-to-buffer" etc.
Then we are free to implement and choose the "main" implementation of
the API, most likely at first the VC version, since it is the fastest
one.  Later, other notions of projects could be added.  However, I don't
want to step too far into Dmitrys domain without him chiming in.
