Perhaps the real answer is to grandfather in non-wilderness corridors say, 100 meters* either side of the road/trail. Look at either side of the road on the Glacier Point topo. WMT, just like the HD trail, is not wilderness, at times it's a freaking narrow superhighway to a specialized tourist destination. A specialized tourist destination that we are loving to death.
* Meters - eventual standard measurement. 100M is about a football field in length.
