Did you see the latest discussion from the National Trust and the OSM’s Data Working Group (DWG) on https://www.openstreetmap.org/changeset/135290950?

The National Trust (via AWMapper) have said that path restoration has taken place for this path, and that they are looking into signage.

That does not stop you from walking along this path if you really want to, but it does make it pretty clear that the path should not be on a public map. Putting it on a public map effectively encourages people to use it.

Do you have any response to their points or the discussion as a whole?
