Well, have you tried implementing Path? ;)

Honestly, that requirement makes things more complicated than what
they need to be (and Path is already hard enough, what with no base
abstract classes directly usable).

My generic (final!) implementation does not obey this requirement
(empty means empty), and I am only saved by the fact that trying and
manipulating paths from different providers together throws a
ProviderMismatchException...
