I think that the issue of searchability and signature are pretty
compelling reasons for such a simple feature to be part of the
function name.

I would absolutely agree with that if all three function were in the same namespace (like the string methods referred to earlier), but in this case, one is a built in and the others will not be — which makes a huge difference in discoverability.

Imagine someone that uses zip() in code that works for a while, and then discovers a bug triggered by unequal length inputs.

If it’s a flag, they look at the zip docstring, and find the flag, and their problem is solved.

Is it’s in itertools, they have to think to look there. Granted, some googling will probably lead them there, and the zip() docstring can point them there, but it’s still a heavier lift.
