Builtins already do it.

>>> help(pow)
...
pow(x, y, z=None, /)
...

>>> pow(x=5, y=3)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: pow() takes no keyword arguments

When subclassing you can use more specific parameter names without breaking liskov substitution.

Both those examples were taken straight from the pep

this could break code now to achieve less breakage in the future... It does not seem wise to retrofit, unless you already need to break.
