Hello welcome to OSM. In this changeset you have removed trails that you believe "unmaintained, undesignated, and potentially hazardous trails" These are invalid reason to remove trails that exist on the ground. If it exists, it should not be removed from OSM.

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

You can also use other tags like "Trail Visibility" "smoothness" to better describe trails that exist but are potentially hazardous. You could also use other feature types, like "informal path".
