It is goods news, definitely.
But it's counterbalanced by what possibly prompted this change in legal status:

The Lordenshaw rock is aleady scheduled, as is the whole area around it, but the carvings have been recently vandalised.
In part, that's 'cos there's a decent sized carpark there, so the rock is easily accesible to groups of radgies. The damage might also (ironically) be partly because there's a small old ministry of works sign there telling visitors it's an offence to damage the carvings. This could act as a challenge to a particularly type of annoying mentality.
It's also salient that there's no habitation nearby, so no farmers to keep an eye on things.
