I've noticed there is a lot of fallout from the changes in #117772 expanding redundant import checking. See discussion and backlinks on that issue as well as #118692 for some evidence.

I have a theory that redundant imports should be split out into their own lint group (this was discussed in the past), and that in the future as a matter of policy, disruptive expansions like this should come with a machine-applicable fix to make rollout smoother.

For now, I'm opening this issue to collect data and feedback that I want to use to inform future policy discussions around lint expansions.
