I move that we stop stripping the files.  Stripping them is saving us
only a few hundred kB out of 25 megs.

That's out of a full installation; in Debian, the "core" macro packages
are in groff-base, and only doc{,-old}.tmac are shipped there.  So for
at least some distributors, people only get the bulk of these stripped
macro packages when they're asking their packaging manager for something
non-minimal anyway.

As for groff-base and whatever its counterparts may be in other distros,
we should weigh the ~75kB cost of leaving it unstripped versus the
benefit of making the package more user-readable for the inspection of
prospective man page writers who'd like to write in mdoc instead of man,
so that they can learn and become more comfortable with it.  (This is me
shamelessly pandering to Ingo.  :P )

The numbers below are in bytes.
