My feeling is that limiting it to strings is fine, but checking those strings for resembling identifiers is pointless and wasteful.

Sure. The question is, do we have to support uses where people intentionally smuggle non-identifier strings as keys via **kwargs?

I'm not saying we need to guard against it, only asking if we need to officially support it. The discussion on Python-Ideas is (partly) about making this a language feature.
