Hi there and welcome! Could you provide some links to the changesets where these discussions are occurring, for context?
Edit: see also this related topic about removing said tiger tags.
My opinion is that you can remove all the tiger tags provided a few things are true:
- A
surface=*is tagged. You can usually identify paved from aerial - Centerline correctness. The route is well mapped to the center of the road without extra nodes
- Street Name verified. The street name is valid.
