that the code removal of nova-volumes is not the only change from essex to
folsom.. if we had deprecated all other changes, this particular one would
not be painful at all.

I believe it wouldn't be an issue if people were not using OpenStack, but
we are..

It doesn't really mean a good thing, since I don't think that the others
upgrades were good, based on what I heard and experienced with sysadmins
from my team...

I agree! (finally :P)
I also think that it's our responsibility (as developers) to ask for input
from operators, it's not because they are not complaining that things are
going smoothly. We should ask for every one we know who's working with
OpenStack and do our best to get feedback.
