For example, inspect.getfullargspec, inspect.Signature, and indeed types.FunctionObject and types.CodeObject have no currently defined mechanism for communicating that a parameter is positional-only.  I strongly assert we need such a mechanism, though it could be as simple as having the parameter name be an empty string or None.

inspect.Signature does have support for positional-only arguments, they have inspect.Parameter.POSITIONAL_ONLY as their kind.  The others probably don't have support for this kind of parameters because there is no Python syntax for creating them.
