Yes, the value of Concepts mostly comes from the, um, concepts that group together a set of traits that characterize a particular category of types. Like input range, forward range, or output range. It's of more limited utility for testing traits individually. You're not really thinking in terms of individual traits, at least not directly, when you're using Concepts; you're thinking in terms of the conceptual abstraction that the Concept represents. The compiler does the checking of individual traits for you.
That's true but it changes nothing about what I wrote. Just replace "hasPrefix" with "hasInterfaceA". The points I brought up remain.
