(Review requested)

For overgrown sections, there are some alternatives to deletion which may apply here:
https://wiki.openstreetmap.org/wiki/Key:overgrown
https://wiki.openstreetmap.org/wiki/Key:obstacle
https://wiki.openstreetmap.org/wiki/Key:trail_visibility

If you feel that any of those apply, it's probably worth adding a check_date tag as well.
