respectively)
This selector is not used for these 2 receiver types in the standard
image (except for one unit test), I never saw it being used in actual
code.
These are just aliases that add nothing but cognitive load.
They make the API's of two important hierarchies (and especially the
interface for non-inheriting classes) heavier than needed for no
functional benefit.
