I'd be open to any of the following:
  a) Hard-error on a qualifer/bindingannotation on types
  b) Support qualifer/bindingannotation on types, but fail if it also
exists on the variable

Though, since this'd be a change to the way jsr330 things are interpreted,
seems like it'd be best to poll the jsr330 folks and make sure all various
implementations (Dagger, Spring, etc..) are on-board with the same solution.
