The selection course has been made substantially easier in the last decade or so anyway, even before this announcement. Once the LRRP role was usurped by UAVs, there was no need to select soldiers for their ability to carry large loads over long distances, so they shortened considerably the speed marches. The modern kit makes the conditions far more comfortable, and they even get water breaks now instead of having to carry or scavenge it all. The selection was probably at its most difficult in the eighties and nineties, when the core role was long range unsupported reconnaissance behind front lines.
