Not if you simply want to link against an installed Python.

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

Nor so if you want to build against 2.1 2.2 and 2.3 ... libraries.

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

There are subtle changes that bite you in the ass if you don't physically copy the right source forward.

For example?

We did copy forward main.c, but found that every time we updated Python, we had to "rehack" main to make sure we had all the options and flags and initialization straight.

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

I think the hook is extremely cheap, very short, looks almost exactly like PyAtExit() and solves the problem directly.

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.
