The reasons for my change were that the path was mapped in the conservation area's public access plan as a trail to be closed and that the path has not been mapped as an existing trail or unmanaged route in official documents since as late as Feb 2020. The path was brushed out at one point, but most of the debris has been moved out of the way over the years by trail users, many of them probably following the AllTrails (and Strava?) route up that path. If you prefer it to be open, I will do that, but I suggest at least that it be tagged informal to encourage people to use the designated Antoine's Summit Trail and not move through otherwise undisturbed wildlife habitat.
