I don't see any use for the vector->string conversion to happen in the
interactive spec: I think the most important use cases for accepting
vectors is when these come directly from Lisp, in which case having to
convert them back to the KBD syntax (only to hope `key-parse` will
correctly undo the damage) is just a waste and a hurdle.

Obviously, I disagree: the vector format is not going anywhere, so it
makes a lot sense to accept it, even though I fully agree that guidance
should never suggest the use of the vector format.
