The Barf route case was discussed extensively at the time. It's one reason
why Andy's useful maps has an overlay for such ways, but does not show them
automatically.

I wrote a couple of diary entries about identifying paths with steep
sections:

There were many interesting posts on Mastodon, especially mastodon.scot,
from experienced mountain leaders. Not only about the specific Lakeland
cases (not just Barf), but also general observations about OSM tagging and
cartography. These were quite difficult to discover at the time because
they weren't always replicated to the OSM Mastodon instance.

On the original question. Our usual advice to landowners is that paths
visible on imagery will be re-added if removed, and that visible notices
regarding privacy etc. are more useful where they don't want members of the
public such paths. This isn't the case here. The way has been retained, but
access tags added, which at least at one time reflected on-the-ground
notices. Clearly the National Trust's intent is that the line of this path
should disappear as it is allowed to recover.

We know that there are other, more problematic, paths on the National
Trust's estate. These are mainly public rights of way which are either
eroded or pass through delicate ecosystems (rare plants, ground nesting
birds etc). AFAIK there is nearly always a nearby alternative path, and
often easier to follow. I don't know what their current standard is for
tagging such paths. However, they have been engaging with OSM, mainly
through OSM-UK, for well over 6 years. They presented their initial plans
at SotM-19 in Heidelberg. Roll-out was hampered by Covid-19, which was a
shame. John Stanworth and I attended an early event organised by the NT GIS
team for NT volunteers and rangers at Clumber Park about 6 years ago. I
suspect that there will be scope in the future for active mappers to help
rangers and volunteers where there's a lot of NT land local to them.
