To me, it is a version number.
mmap() and mmap2() both have 6 parameters.
Besides if wait4() were born before wait3(), would it still be wait4() :-) But I see that it is hard to get one-convention-that-fits-all.

And extended assumes we wont extend again.
An informal poll of reviewers has clone3() with a slight advantage :-)
clone_extended() camp: Serge Hallyn, Kerrisk, Louis Rilling, clone3(): Sukadev, H. Peter Anvin, Oren, Matt Helsley.
I like clone3() but am not insisting on it. I just want a name...
