My US database is currently catching up with reality, so I can't really try until that has completed, but I do have an idea how to make that work. Without relying on human tagging like in the Inspektor. What I would do is select all (current) ways that overlap the bounding box of the deleted way and that are created after 7/15, then calculate the hausdorff distance between the deleted way's geometry and the results of that query. If we get a close match, it is *very likely* that the way has already been remapped. Identical highway= tags may further corroborate this. What I am not so sure about is using the non-compliant geometry and tags this way, from a legal perspective. Anyone who can offer any ideas on that?
