the ways I tagged as abandoned are almost completely washed out and not useful to most people.  here is a pic of Way: 1290305051  https://imgur.com/a/XBMSg3w  do you have any reason to tag this as highway= path i don't think that describes the condition very well.
I think abandoned:highway = track would best describes that.  Way: 1290305049 that I had tagged as disused is in better condition but not used I would be ok with dual tagging that one.  Also would be interested in what your source for lidar imagery is usgs 3dep or something else?
