I didn't know about that API, yet. Where can I learn more about it?

Could those custom unwinders also solve @medismailben's CPython-frame-debugging use case?
If not, what would it take to make custom unwinders fit that use case?
Should we maybe extend the custom unwinder support, instead of introducing a new "frame provider" concept?

That would be amazing. Is there any relevant documentation / examples where I could learn from? E.g., in Apple's open-source LLVM version? Maybe there are even publicly available design documents?
