Well also by being able to play more than atleast 1 instrument shows that you are very instrumentally talented
Also, I somewhat agree that if someone plays one instrument, they can focus on it more than someone who plays six or so different instruments can. But that doesn't mean that they do. Someone who can play one instrument may focus on their instrument alot, but that doesn't mean that they are better on it than a multi-instrumentalist, who play the same instrument as well as others. It simply means they have the oportunity to.
