I see, but that's not what you're suggesting. You're suggesting that how 
command search and execution works be changed to allow functions that 
contain slashes in their names to prevent command search, and shadow 
filesystem entries including those of standard utilities.

The fact that bash and zsh already allow it doesn't mean it's a good 
idea. And it's easier to make the overall behavior unspecified than 
examine each shell and document this new behavior; preferable too 
considering how little it benefits the user.
