Is coreutils' maint.mk essentially a superset of gnulib's, then?

Perhaps; but it's not clear to me why it's necessary to delete the
existing rules from gnulib in order to migrate them from coreutils.
Can't we just migrate any changes to them one by one?

Since the Gnulib usage model involves grabbing the latest via Git or
CVS, I would expect Gnulib's repos to be in a pretty stable point at any
particular point in time. If you apply the proposed patch, then anyone
who does a pull and a gnulib-tool --update may be surprised to find
their favorite maint.mk rules suddenly vanish, until such time they are
reinstated from coreutils.

May I suggest that, if it is really most convenient to do it this way,
the mainline repo be cloned to a special-purpose one to work on this, so
that the mainline itself may retain full functionality, and that
coreutils use that one during migration to gnulib's maintainer-makefile?
