I used that initially, however I wasn't paying attention and reverted them in the wrong order resulting in some errors in the changeset tags here: https://www.openstreetmap.org/changeset/164444118 

Since https://revert.monicz.dev only allows reverting a maximum of 3 changesets at a time for users with less then 500 changesets on their account, in order to revert 8 changesets I would have needed to do 3 separate reverts with a minute or so wait in between to let the overpass server it uses for calculating reverts sync with the osm server. So it would not have been that easy.

I also tried https://revert.osmz.ru but it said my revert was "too big."

With https://github.com/Zverik/simple-revert I was able to revert everything in one go, though it did take a very long time to calculate the reverts.
