I think this is connected to #2205 in an interesting way. The question that arises is if one MUST include all ACK state between highest received, and the lower PN that needs to be ACKed (as it is newly arrived due to reordering). 

An alternative would be to explicitly allow GAPs for packets that has been received and where the reception's ACKs has been ACKed. But, I guess that results in interesting bookkeeping chores in the implementations.
