A bundle nothing would deliver is refused at registration (hq issue 216)

The composer delivers a bundle when the runtime loads from it, a resource names it, or it is the
runtime; one reached by none of them was built, recorded and pushed as success and was simply
absent. Seven modules' tools went missing that way. Refused at registration, naming the field that
would deliver it.
