@Content Complaint (komoot) - Not sure exactly what "this is a footpath and therefore only accessible by foot" was supposed to mean?  It's tagged as a "path" (unusual here, but some people use it), with foot access only on it.  Are you saying that it should be tagged as something else?  Do you have feedback from a Komoot user that said that they thought that they could use another transport mode here and it turned out they couldn't?  If so, it'd be good to get the Komoot user to update OSM with what else they know.  As previously mentioned the OS maps that you link to are not suitable for use in OSM.
It's a while since I've been here but I have walked it a couple of times - my recollection is there's a pretty clear footpath round from Twmpa / Lord Hereford's Knob to here, and that it's some of the "paths" down the valleys that are a bit iffy.
The fact that this way was originally mapped from Strava rather than survey was a bit worrying (Strava doesn't show "paths" - just places that lots of people have gone, including illicit shortcuts), but this one does really exist.
