ejont (2019-04-04 16:59:13+00:00): These are the changesets with deletions that I've found. This is surely not a complete list, the method was simply to look at orphaned nodes (nodes not part of any way) in overpass-turbo with this query:

[bbox:{{bbox}}];
way; > -> .w;
( node(if:count_tags()==0); - node.w; );
out meta;

The list with changeset, username, what was (partly) deleted, is it fixed?:
