If it's only a warning, I worry that if we stop checking the flag bits it can cause wild pointer following. This sounds like it would be a potential security issue (load a module, ignore the warning, try to use a certain API on a class it defines, boom). Also, could there still be 3rd party modules out there that haven't been recompiled in a really long time and use some older backwards compatible module initialization API? (I guess we could stop supporting that and let them fail hard.)

As far as I can tell, all the legacy APIs were removed when PEP 3121 was implemented (Python 3 allowed us to do a clean break here).
