The issues that Scala and C++ have are far beyond just "having generics". Classical (ML-style) generics are an incredibly simple feature, much more so than, say, built-in channels.
I'd say typeclasses, templates, and variance have, sure. Those are separate features from generics in my mind. (But you could reasonably lump them all together under the heading of "generics" and I won't argue too much.) :)
