    Currently __text_signature__ can be used for specifying signature of functions implemented in C. It is ignored for functions implemented in Python. The proposed PR allows to override the real signature of Python functions by setting the __text_signature__ attribute. This is needed to restore useful signatures in functions that use the *args hack to implement positional-only parameters. See the discussion for PR 12637.
