Along these lines, I've been contemplating proposing that Clinic specifically understand "path" arguments, distinctly from other string arguments, as they are both common and rarely handled correctly. My main fear is that I probably don't understand all their complexities either ;-)
Anyway, this is certainly something we can consider *improving* for Python 3.4. But for now I'm trying to make Clinic an indistinguishable drop-in replacement.

Naturally I agree Clinic needs more polishing. But the problem you fear is already solved. Clinic allows precisely expressing any existing PyArg_ "format unit"** through a combination of the type of the parameter and its "flags".
Very nice then! Your work is promising, and I hope we'll see a version of it some day in Python 3.4 (or 3.4+k).
+1 for getting this into 3.4. Does it need a PEP, or just a bug tracker item + code review? I think the latter is fine -- it's probably better not to do too much bikeshedding but just to let Larry propose a patch, have it reviewed and submitted, and then iterate. It's also okay if it is initially used for only a subset of extension modules (and even if some functions/methods can't be expressed using it yet).
I don't see a need for a PEP either; code review should be plenty since this doesn't change how the outside world views public APIs. And we can convert code iteratively so that shouldn't hold things up either.
