Yes, I have been there on 2024-12-29, walked from Lokavec by the hiking path to Sv. Urban and back by the road. On that same wiki page that you cite, on grade1, it also clearly states "Usually a paved surface".  "usually" is not "always" or "must be". At least a section of the road from Lokavec to the plateau/parking I consider to be better than tracktype3, as is now tagged. But I'll let you be the final judge. Regards Mark.
