It's easy to use on a per-file basis, and in the majority of cases
allows the source to be transparently backwards compatible with
older/other versions of Emacs; so why not. Since it's a fait accompli,
discussing alternative ways it might have been done are only going to be
of academic interest.
I never did get an answer to my question about whether the setting HAS
to go in the first line of the file though. I still don't know.
