 We're not meant to be porting anything that can be done via neutron or
only supports nova-network anyway. Someone who wants to use nova-network
will have to use the V2 api (and nova-network is meant to be going away
soon anyway). I think that means ips.py will stay, but fixedips will be
removed (fixed_ips was the first extension to be ported before we'd decided
what we were going to do).

-          The API to list scheduler hints I was thinking about merging
into the scheduler_hints extension, but that is tagged as “move to core”,
but its also been already ported to a v3 pluggin.   Does this mean its not
now going into
core ?  (keypairs & console_output are in the same state BTW)

We hadn't managed to work out what was going to be core and what wasn't
before we'd ported most of the extensions so there is still some work going
on to move stuff in (and more importantly out) of core. The concept of
"core" is a bit different in V3 because everything is now a
"plugin/extension". Core is essentially just the hardcoded list of
extensions which are always loaded. We do have to do make some changes
where a plugin contains a mix of core and non-core functionality to
separate the two.

Yes, post Havana release we will have to start bumping the version numbers
when we make changes (and even then we are limited to what we can do). So
if anyone sees anything that doesn't look right, please yell :-)
