Does this project obsolete 2002/278 (Singleton IPMP Group) and
2002/763 (Contract for use of SIOCGLIFGROUPNAME)?

Is there a new contract to replace PSARC/2002/763-01?

It's good that we have the affected teams talking, but I think
completing the case will require a follow-up.

This will remove information that used to show up in the MIB, and thus
cause a small loss of observability for IPMP machines managed by SNMP.

I think we should have ARC advice added to the opinion: management
needs to be advised that while this is an improvement in accuracy of
the data, it's also a regression, and that we need to have updates to
the SNMP implementation to support IPMP (perhaps via a private MIB).
