What I meant is that it's difficult for me (and perhaps others) to
assess how much more practical your patch makes it to create C types.

Hmm. That public interfaces take pointers is one thing, but that doesn't
mean the PyTypeObject structure itself must be concealed. It could be
exposed as an implementation detail.

Please note that your approach will make it difficult for third-party C
extensions to remain compatible accross several Python versions (those
before and after the API switch). While we sometimes change or deprecate
APIs, we never do it as massively as that (even the 2.x -> 3.x
transition is quite gentle).

I meant "large" indeed :)

Well, a nosy+ bumps up the issue at the top of the recently modified
issues, which means other people notice it as well.
