I guess I can implement opt-out - can you post list of ways which you want to retag to sidewalk=none in https://community.openstreetmap.org/t/sidewalk-none-to-no-proposed-automated-edit/128842/ thread?

I guess that I can also exclude ways you last edited but in such case when someone else edits way it will be later retagged

In either case this can be still retagged manually
