An autofs 'rmdir' is really just an expire, isn't it? It doesn't
really change anything in the parent, and a lookup will just reinstate
the directory.

So I'd go the other way, and say that the strange thing is that it
changes mtime...

That said, exactly *because* it changes mtime, I think the real answer
is that none of this matters, and it's probably just an oversight, and
it could easily go either way.
