The "discoverable features" API handles how clients access the myriad features we offer, without simply adding a million has_FOO and do_FOO methods to radio_control and multi_usrp. discoverable_features allows clients to query the existance of, enumerate, and ultimately they get (by enum or by type) an object which implements their wanted feature.
