I note that the I-D referenced above allocates 32 bit for the zone index which
will suit a few implementations and not suit many, unless the intention is to
use
the SNMP ifIndex and map from that to the string used by such implementations.

Hopefully, 6man will be invited to review this as and when it progresses,
otherwise it will have to be at IETF Last Call:-(
