As a reminder, we have two options in the draft for adding support
of IPv4 prefix management:

1. Add a version number flag to the objective
2. Add a second objective specific to IPv4

So far the preferences I have heard (including my own) are for option 1,
because it's simpler to implement. I think the authors will go that way for the
next version, but of course it's a WG choice. Comments please!
