Anyway, I don't like the idea of making interfaces concrete. That means
that a user could directly instantiate an interface which doesn't make a

Concrete doesn't mean "instantiatable by the user". It means
"instantiatable period".
Interfaces are not supposed to be instantiatable by anyone. The fact that
object_new() is used to create the interface is an internal implementation detail.
Interfaces are stateless and by definition, never have an implementation on
their own. So object_new() of an interface type directly results in a useless
object.
