That would make the var impossible to use from the shell.

And no matter what the name is, if it makes a standard
utility behave in odd ways, it'll break scripts that
don't expect the odd behavior.  That's the essential
objection here.

Yes, we've used env vars in the past for this, but we've
come to regret it, and we don't want to make matters worse
in this respect without a compelling justification.
