_PyStack_AsDict() doesn't check anymore if keys are unique. BUILD_MAP_UNPACK and BUILD_MAP_UNPACK_WITH_CALL opcodes now use PyDict_Update() to combine mappings and _PyDictView_Intersect() to check if keys are unique. I don't know if there is still something to optimize. The opcode changed the method to C and Python functions (FASTCALL) changed a lot recently ;-) I suggest to close the issue.
