This happened despite tens of thousands of users, years of good reviews, and an extension so useful that Google's own accessibility team demos it at conferences.
I was only able to get the situation sorted because I know people who work at Google on the Chrome team. Even with all this, it took weeks to get the previous version restored, and after that weeks more before we could push an update without having it get automatically rejected.
The only "good" news is they didn't uninstall our existing user base.
