Adding new protocol requirements is now a "binary compatible
source breaking change" without explicit guarantees about
source compatibility.

Removing a default from an associated type is not binary
compatible because the associated type may itself have been
added resiliently, in which case clients that predate the
associated type will not be able to instantiate a witness
table for the protocol.
