Whoops...I had meant to link to "https://review.openstack.org/163060" and 
managed to miss the last character.  My bad.  The API change I was talking about 
has now been split out to "https://review.openstack.org/168418".

I haven't proposed any features (with spec/blueprint) for kilo or earlier.  I'm 
planning on proposing some for the L release.  (Some are already in for review, 
though I realize they're not going to get attention until Kilo is out.)

I may be making invalid assumptions about how long it takes to get things done, 
but if so it's coloured by past experience.

Some examples:

I proposed a one-line trivial change in April of last year and it took almost 2 
months before anyone even looked at it.

I reported "https://bugs.launchpad.net/nova/+bug/1213224" in 2013 and it hasn't 
been fixed.

I opened "https://bugs.launchpad.net/nova/+bug/1289064" over a year ago, 
proposed a fix (which admittedly had flaws), then handed it off to someone else, 
then it bounced around a few other people and still isn't resolved.

I opened "https://bugs.launchpad.net/nova/+bug/1284719" over a year ago and it's 
not yet resolved.

I opened "https://bugs.launchpad.net/nova/+bug/1298690" a year ago and it hasn't 
been touched.
