If a stripped down API like this is intended as "use this and you get
compatibility across multiple Python interpreters and multiple Python
versions" (essentially a much stronger and more effective version of
the stable ABI) then I'm solidly in favour (and such an API has clear
trade-offs that allow people to judge whether it's the right choice
for them).

Having this alongside the existing API, which would still be supported
for projects that need low-level access or backward compatibility (or
simply don't have the resources to change), but which will remain
CPython-specific, seems like a perfectly fine idea.
