Mostly it's a matter of taste.  It introduces yet another set of
tokens that you have to escape to use literally in prompts, and I
don't think the prompt is an appropriate place to be running command
substitutions.  It means even more possible collisions on variable
names with unintended side-effects.   Obviously these are things that
can be avoided; I'd just rather not have to think about them.
