While I think we should squash a lot more meat into our Versions, once its
in the ancestry, it needs to be in the Repository.

It's fine to skip numbers but, if, by 'absence', you mean a VersionInfo in
the ancestry which is absent from the Repository, then no, it is not robust
to that and represents an incomplete and corrupt code model.  Please don't
allow this to happen.

This came up last year, after a long circular discussion, we realized MC
does indeed handle duplicate filenames (by automatically renaming as
necessary).
