I suppose it could.  But the rebase package was developed to address the
rebase problem for Cygwin packages that are part of the distribution.  That
includes perl.  But perl can pull in its own stuff, particularly stuff that
isn't in the distro.  The rebase package would have to be taught how to find
and handle those.  Presumably, this could be done by leveraging what
perlrebase does but that requires coordination and effort, even if Reini and
Jason want it to happen.  It's really their call since it's their packages
that would be directly affected by any work to address your question.
