text: No, in OSM we map what is on the ground. Anyone attempting to follow the actual PRoW alignment is going to find it very awkward struggling through the trees (it's an orchard not a field). Standard practice is to remove highway=path or footway leaving the designation tags & add a separate path/footway showing the actual on the ground alignment (discussed with examples on talk-gb in the past).
  
  It is not uncommon for actual paths to diverge from an alignment drawn on maps by parish councillors in the 1940s and 1950s. This does cause problems when work is done (as the HA may insist on reinstatement on the definitive line), but most of the time landowners/walkers/PRoW officers live & let live.
