These are not mutually exclusive. You can regenerate IN.py and still
add the constants to the socket module.

Neither do I. In the specific case, I'd generate four versions of
CDROM.py (with differing names), and provide a CDROM.py that imports the
right one.

I disagree. It's limited, not wrong.

These are problems, but not necessarily issues. Even if some of the
values are incorrect, the values that are correct may still be useful.
