This is something that worries me, in that the IETF seems to be 
deserting the IPv4 market sector before it is clear that the market is 
fully committed to an IPv6 only world.

Certainly a lot of enterprise networks and SP cores are still IPv4 only 
with no apparent intention to shift in the near future.

Markets and standards, like nature, abhor a vacuum, and if we do not 
continue to serve the IPv4 needs some other (quasi) SDO will appear in 
support of users with requirements and vendors that never leave money on 
the table.
