>From a Cinder prospective, I think that doing this to the Cinder codebase
at this stage would signal the beginning of a rapid death spiral for the
project. We've already got issues with consistency of implementation and
the fact that some things just plain down work on some drivers/backends.
Third party CI took massive effort but should allow us to focus on some of
those things and clean them up.

If we required third party CI to pass for every core patch when the drivers
are all in separate trees with their open code merging strategy/team, then
progress would quickly slow to a halt due to the time and effort it takes
to get a change into every driver, not to forget the effort required to
make every change back compatible with the old and new driver since they
aren't released in perfect lock-step any more.

If we allow third party CI to fail and wait for vendors to fix their stuff,
experience has shown that they won't, and there'll be broken or barely
functional drivers out there, and no easy way for the community to exert
pressure to fix them up.

Either of these is a death-knell for Cinder.

I don't follow Neutron closely enough that I can comment on how this
might/might not affect them.
