Good point. I will hunt them out and post here. > Every new rollout will cause some issues.

My impression (and it is only an impression) is that the main issue is with people being taken by surprise with new behaviour, which is a combination of things: 1. Poor communication (as noted earlier, we struggle to even reach many of our users) 2. A general principle of "you should use the latest pip" (i.e., our check and warning for if you're using the current version) 3. People using pip in ways we didn't consider I think it's important that we don't let the standardisation and improvement process get stalled by a fear of affecting people's workflows, but at the same time I think we should consider transition paths.
