It adds complexity because the number of `non local' things you have to worry
about to determine what happens when you save a file has increased.  I'd
guess that man people have been surprised by write-file-functions, but by now
know to look there if something funny is happening when they save a file.
If you add _another_ hook, then they have to repeat the process (be confused,
whoa, write-file-functions is nil, be _really_ confused, ..., eventually
realize there's now before-save-hook too, be enlightened).

That said, maybe it's worth it, maybe it's not -- maybe simply being very
careful about verbosely documenting things would be enough -- but geez, give
Stefan some credit!
