Hi Murray, Thanks for the review. The normative SHOULD was used because it is possible to operate in Port-Active mode without the P/B in Ether A-D per ES (if port-active is setting the interface Down then the peer will not send any routes – there is no ‘B’).
It is just undesirable for convergence: the P/B give a hint to the remote that the entire port is Primary vs Backup, and that it need not wait for each individual Ether A-D per EVI update to P/B. All implementations I am aware of are doing it, but I should still circle back to co-authors/implementors before flipping it to a MUST.

When might an implementer or operator decide to do otherwise? Same question around the SHOULD in Section 4.1.
