are not second class citizens in term of call performance.
These PEPs proposes new public protocol which can be implemented by 3rd party extensions, especially Cython. In this meaning, it's not used only *internally*.
I think Mark meant that the API should *also* be used internally, in the same way that external code uses it. Meaning, there shouldn't be a separate internal API.
