No, this is not an appropriate use case for generic protocols. (Nor is 
Generator/IteratorProtocol, for that matter.)

Generic protocols would be for cases where a single concrete instance can 
conform to a protocol using several different types. Genuine use cases for that 
do exist, but they're few and far between.
