Not really.  While I _do_ think direct testing has merits, I think
that should be done by adding direct tests, not by removing the
tests that are meant to protect higher level _users_ of the
underlying mechanism from breakages.  After all, their breakages may
not come from new breakages of the lower level mechanism (i.e. the
mailmap.c code) but the way these higher level code makes calls into
the mechanism, and direct test of the lower level mechanism will not
protect them from the latter kind of breakages.
