Sure, but partition + "in" (now that it works as an arbitrary substring test)
seem to cover a very large subset of the things you'd want to do with find:
enough that having only index available for the remaining cases is unlikely
to hurt much (apart from the important issue of backward compatibility, but
this *is* py3k). I'm having trouble thinking of any plausible counterexamples,
though I'm sure there must be some.
