That's the difference. You can't fold templates because they're binary

They're not always binary-incompatible. For instance, if a template only works
with pointers or references (this includes object references) to parameter types
it might well contain the exact same machine code for some of the instantiations.
If you require that the class inherits some interface and call that interface's
methods, they'll be incompatible. I'll dare to say this is the most useful
variant of generic code.
Okay, so it doesn't (usually) work for interfaces, but it'll work if the
requirement is for a common base class. Or perhaps even if they happen to have a
common base class that implements the interface in question.
