FWIW, I would personally be ok with the vague definition. First, I
don't think that apps that use command line or other textual interface
to specify an output are a thing. We're aiming for a graphical user
interface, after all. Second, even if they are, the app can still offer
shorthands for the possibly complicated "names", e.g. by using the
wl_output global's name (uint). A CLI would need an option to list the
possible outputs for a user to pick in the first place.

The only thing I could criticise there is, is it really "name" or more
like "description"? One still requires them to be unique anyway. I
think calling it "description" would make people expect less of a
standardized or single-alphanumeric-word spelling. But I won't insist
on it.
