@CRCulver - can you point to where this tag was deprecated? I'm not seeing any consensus that the tag should be deprecated anywhere. The wiki still lists the tag at https://wiki.openstreetmap.org/wiki/Tag:crossing=unmarked and ID Tagging Schema still offers a present for the tag https://github.com/openstreetmap/id-tagging-schema/blob/main/data%2Fpresets%2Fhighway%2Fcrossing%2Funmarked.json
