We've definitely held the stance that NO_PERL doesn't mean to disable
perl in tests. For casual use of perl in installed shell scripts, on
the other hand, I suspect it was more that we forgot about them than
that we had decided one way or another. :)

Yes, that sounds good to me. (The status quo also seems fine to me,
but I like that this proposed approach would simplify things a
little.)
Thanks for working on this, and sorry for the earlier noise.
Sincerely,
Jonathan
