-1. Yeah, you could reject "\pset true 'f'", but what about
not-obviously-different values such as 'f ', or f with a non-breaking
space, or f with a tab, or yadda yadda yadda?

I went on record as opposed to this entire idea back at the start of
this thread, precisely because I was worried that it could lead to
confusion. And I remain of the opinion that it's not a great idea.
But if we're going to do it, let's not bother with any fig-leaf
proposals that pretend to partially guard against confusion.
