For what it's worth, I don't think that this belongs within the
protocol. The protocol should make it possible (maybe via a
negotiation), but the decision needs to be left to the hosts (and their
parameters/options). They might want it in some cases and in some cases
not. It depends on the 'costs' associated with the ULID pairs.
