I've posted this to the PR, but adding it here as well: I think this is a situation very similar to the case with functools.partialmethod, where you're going to need to write a separate functools.singledispatchmethod class that's aware of the descriptor protocol, rather than trying to add the functionality directly to functools.singledispatch.

I agree with Nick here. Adding a separate decorator looks like the right approach, especially taking into account the precedent of @partialmethod.
