I think you are going a bit OTT. This is one hold on one route. The old hold on grit does brake from time to time, but it certainly isn't a regular occurrence, especially given the volume of traffic at popular locations like Stanage. Care needs to be taken yes, but like climbing on loose limestone? I think not. Half the joy of grit is the fact that it isn't loose limestone.
