If it's going to be harder for CPython, then I wouldn't worry about it
too much.

I can't see any good reason to write to .metadata, so a PEP note
("Making changes to sys.implementation.metadata is not guaranteed to
work" or some such) should be fine. If it somebody tries to do it and
it breaks, well, they get to keep the pieces. :)
