What is that winter wind going to do to an injured person or someone who is too weak to get down?
Make him feel uncomfortable, but of course he or she will have gear to help survival. They could of course go to the filthy vandalised hovel* some well meaning idiot built up there, but it was on the far side of the plateau, further than the shelter of lower ground. This idiocy stopped in the 1970s for very good reasons (see above)
For crying out loud, this is Kinder you are on about... What next, Long Mynd, Cannock Chase? I'd stay at home if I were you.
