PEP 570: Python Positional-Only Parameters

[guido (Guido van Rossum)]

There’s a big difference between encouraging it and changing the grammar in a way that lets someone else decide whether I can or not. We can still say it’s ugly, un-Pythonic, and plenty of other things without having to make it literally impossible.

Literally the same argument applies to accepting the PEP – you don’t have to use the new feature.

When it comes to who can control how a function can be called, obviously that should be the author of the function, not the caller.
