After spent several days to read PEP 580 and your implementation, I think I can implement it. I think it's not easy, but it's not impossible too.
The signature of "extended_call_ptr" in PEP 576 is almost the same as the signature of a CCALL_FUNCARG|CCALL_FASTCALL|CCALL_KEYWORDS function in PEP 580 (the only difference is a "self" argument which can be ignored if you don't need it).
So, if you can implement it using PEP 576, it's not a big step to implement it using PEP 580.
