One of the hidden costs of an external plugin that things break. This is something that happens to us at least once a week. We have been proactive in this by doing the following:
1. Running the decomposed plugin unit tests with every neutron change - this gives us an indication of which patch broke and why 2. Running the Ci The onus is on the decomposed maintainers. Having said that the ability to actually do some development is liberating.

Where was this made clear? I didn't know about this until it broke and I'm a very frequent contributor and reviewer, which is the core of my complaint. The updated wiki is helpful, but doing it after-the-fact only helps when people try to figure out why they can't make changes to their repos. In that patch there were 3 in-tree third party plugins that had to be updated. That should have given a hint that it was likely to break other plugins as well. The other annoying lesson from that is that plugins/drivers still in tree are getting better treatment than the ones that went through the split process. We need to be much more diligent about announcing these things ahead of time or we need to be clear that Neutron is completely unstable as a framework and third party drivers should basically never import anything from the neutron namespace.

For the second one, I think we made it clear before that no plugins must rely on neutron.openstack.* contents. Now I've made it mentioned at: https://wiki.openstack.org/wiki/Neutron/LibraryAPIBreakage If your plugin is using any of neutron.openstack.* contents, just stop doing it. It's going to break.
