Hello, welcome to OSM. The the path you removed in this changeset seems to still exist on the ground. I checked out heatmap data in that area for the last 12 months and it shows there is still a lot of activity on that tail. https://i.imgur.com/EY2wP3K.png

In OSM if a feature exists if should not be removed from the map regardless if its officially closed. If it still exists on the ground it should not be removed yet.

The correct way to handle closed trails is to use OSM's tagging system. tagging "access=no" would be appropriate if its closed to the public. Once this is done, services that do use OSM data will reflect that and specify their access.

For trails that are permanently decommissioned:
depending on the situation you can add a lifecycle prefix to the highway=* key, such as closed:highway=path or abandoned:highway=path.
