This change and L43 sounds like something specific to Cast; do you really want
to introduce them to this generic interface? Or maybe you should create a
CastRouteDelegate that extends this interface?

Yeah, I think extracting these interfaces was unnecessary as there's only one
implementation of each anyway :) E.g. CastMediaRouteController just uses the
CastRouteController directly.
Eliminating the interfaces is out of the scope of this fix though.
