I think it's also good to think about the actual problem(s) that are being
solved, without going too deeply into the implementation. It might be
useful to look at all the motivating use cases and to make sure this is
really the best way to provide a solution to them.

​How exactly is caching dependent on the proposed ContextKey thing? To
avoid a dict-lookup or similar to get the cached value? But now we need to
look up the key object from somewhere?

Which APIs? The C API you mean? Something that is not in Jim's list?
Something that is (not) in the PEP? People need to get a clear picture of
what is being proposed.
