If you mean like declaring that a shell's overall behavior be unspecified
once a function with a name that wouldn't make a valid variable name
defined or something like that, then yeah, I guess they could say that in
the standard.

But then how would you execute a program that resides in, for example, the
current directory portably? `(exec ./program)`? I don't think that's a good
idea.

I don't have any personal reason to support or not support what you
propose, but that names of functions and pathnames of executables can clash
even under POSIX mode doesn't feel right. I'm not against periods and
colons in function names though.
