Why not? Just don't call the function Py_Main.

Again, I can't see a reason why that is.

For example?

That is not necessary. What would be the problem if you just left
your function as it was in Python 2.1?

Unfortunately, the problem is one that almost nobody ever has, and 
supporting that API adds a maintenance burden. It is better if the
maintenance burden is on your side than on the Python core.

If you think you really need this, write a PEP, ask the community, and 
wait for BDFL pronouncement. I'm still -1.
