I think it's still OK to defer fixing discrepancies between the alternate implementations until people explicitly report a problem, which I guess means the policy update that I'd be looking for is that in cases where the C version currently implements a superset of the Python version's behaviour, the recommended policy be to accept patches to align the two even if: - it makes the Python version more complex and hence harder to read - it makes the Python version slower on CPython (and likely other runtimes without even a method JIT) Replacing a closure with a custom callable (as with the functools.partial patch) is a case where both of those objections legitimately apply, hence making the right thing to do less than obvious given the current wording of PEP 399 - it isn't clear whether those simplicity focused considerations should trump the cross-runtime compatibility ones.
