I think you could keep it light (but +1 for adding cache_tag now).

I'd suggest making it clear that neither the keys, values, nor semantics are
actually being proposed in this PEP.  The PEP could just include some examples
for future additions (and thus de-emphasize that section of the PEP).

It might be helpful to describe a mechanism by which future values would be
added to sys.implementation.  E.g. is a new PEP required for each?  (I don't
have an opinion on that right now. :)
