So I guess the recommendation is to do a fairly heavy press on the brake pedal every so often. Hard enough to bring the rear brakes into play and often enough to clean the surface. Presumably more frequently in poor conditions when road spray and grit will be thrown up onto the discs.

I suspect that brake disc damage is not just corrosion but is caused in part by the disc picking up grit and dirt between infrequent application of the brakes. So when the brakes are then used that grit is caught under the pads and ground into the disc, causing scoring.
