And given the extended pyc header being proposed in PEP 552, we'd be
able to include flags in the header to indicate that the pyc file was
compiled with this alternative behaviour. While that wouldn't be
needed for import, it would be useful for anyone trying to confirm
that the pyc file actually matches the corresponding source file.
