Not necessarily. I chose the "empty directories must be tracked" wording
to avoid that. If the PM were about to remove a directory that wasn't in
the database of empty directories, then it could proceed normally.

If you're asking what problem I was trying to solve by leaving the
implementation up to the PM, then I was only trying not to be pushy. If
the "automatic keepdir" idea...

is workable and if the PM authors are fine with it, then we could spec that.
