With the reply from @oarn, the presented reason for removing the path from OSM is a claim that it should not have been there in the first place over twenty years ago. This is not for OSM to judge. The fact that it is there now was not disputed by @oarn. In light of this, I stand by the conclusion that it should remain in OSM, and that an official verdict will affect the access tagging.
On a side note, the main road should also not have been built this way in the first place. Its actual size, position, and intersections differ dramatically from the plan. OSM should map the world as it is, not as it (possibly) should have been.
