How about: 4. Take 3rd-party drivers to a separate cinder-extra-drivers
repository/deliverable under the Cinder team, one that would /not/ have
follows-stable-policy or follows-standard-deprecation tags ? That
repository would still get core-reviewed by the Cinder team, so you
would keep the centralized code review value. It would be in a single
repository, so you would keep most of the "all drivers checked out in
one place" benefits. But you could have a special stable branch policy
there and that would also solve that other issue in the thread about
removing unmaintained drivers without deprecation notices.
Or is there another benefit in shipping everything inside a single
repository that you didn't mention ?
