It seems to me that RBAs take great care to make accurate cuesheets. Brevets are pre-ridden nowaways to check the directions and also conditions of the route. That never happened in the old days of randonneuring. There are still plenty of cue sheet only riders out there. I cannot imaging them going way on brevets. OTOH...I just wish gratuitous gravel sections were not added or authorized by-passes/detours were allowed/mandated.
