Yes, but the amount of intelligence actually needed is pretty minimal.
(It is actually harder to decide between multiple available global
prefixes, than to decide between global and site local - the former is
a difficult problem, the latter is almost trivial).

But you do trust them to select a suitable outgoing interface, to
pick a usable router, and to choose amongst several different possible
addresses for the destination (over which you most often have no control).
This all seems rather arbitrary.
Forcing NAT on hosts & users because you're afraid that the OS/app
designers can't tell what's global and what is site local seems rather
heavy handed. I'm sure glad I don't have to live with your policies.
