I am opposed to pursing this work at this time. The ongoing discussion on the list suggests that the arguments put forth for WESP use in the OSPFv3 context, the first concrete proposal outside of the middlebox inspection context that motivated WESP, have not been validated. The presentation in Hiroshima listed a variety of possible use cases, without providing any detailed analysis, and at least one such case was considered and rejected by the IPSEC WG on at least two occasions. My recollection is that Pasi agreed with my suggestion that at least 2 or 3 valid use cases need to be thoroughly vetted before the WG pursue this as a new work item.
