It is a no win situation at all levels. If authorities and land owners don’t water down challenges they are accused of failing to aid the less able in some way. If they do, they are accused of environmental damage. Increased access also means damage, no argument possible there.
My take is that any RoW should be maintained to it’s original state and thus purpose. If a small chunk of society doesn’t like it hard luck. Which means that a hundred year old path probably won’t have any surface at all. Great.
But then again isn’t the MTB world guilty of much more? Trail centres where natural animal paths could be used. Digging be it official or illegal
