a. The C-API document doesn't document these functions beyond giving their signatures. This is even true in the development version, as far as I can tell.

Yes. Alas, the documention project for new-style classes is way behind. I could use some help. :-(

b. There is no Python API; you can define a class with some methods with the right names and signatures and it will come tantalizingly close to working for some purposes but sooner or later you find that you just aren't allowed to play as a first-class citizen from Python.

Can you show an example of something that doesn't work? I'm pretty sure this works correctly, as long as you stay far away from classic classes.

Has anyone already done either of these tasks?

On the bright side, I did manage to make a metaclass without my head going critical. Smoke came out my ears, though.

What color?
