I don't think being a function versus a classmethod is important here. Just that the underlying name is *callable*.
But wait a minute, zip isn't just a "callable", it's a class, and adding more methods to it seems perfectly natural, just like lots of other built-in classes.
Zip is a class in CPython 3.8. it may or may not be in other implementations or versions. The API users are currently promised says nothing about it needing to be implemented as a class. Moreover, even if Python 3.9 decides to make zip() a function instead, that wouldn't prevent the alternate constructors being implemented.
