[...] I'm out of my depth here, but the fact you use inheritance means the two types are not the same as a consequence, right? I.e. std::is_name<def#1, def#2> is false?
Correct, these are diferent types.
And I suppose such partial specialization is not possible with template type aliases to have is_same<> being true? Not sure it matters, just thinking out loud.
No, template aliases don't support partial specialization. But I don't see any fundamental problem with subclassing. Joaquín M López Muñoz
