@NTMountainRanger the problem with "just deleting" things like this is that it will not have the effect that you want it to have.  If someone sees a "missing path" from old imagery, they might just add it back.
Your colleagues in England and Wales have worked extensively with OSM (including at least one joint session in Clumber Park in Nottinghamshire, if I remember correctly) - perhaps it's worth chatting with them?
An example of the sort of fix that would work can be seen at https://www.openstreetmap.org/way/1086252957/history and https://www.openstreetmap.org/changeset/135290950 , over Dropping Crag near Scafell Pike in the English Lake District.  "AWMapper" in that conversation is one of your English colleagues.
Best Regards,
Andy
