I don’t think it is cheating if everyone has access. It’s perhaps a competitive edge.
There will always be purists who think eq should be done in a stiff, slick PDN on a high OTTB in a field over big jumps. That’s nice, and probably if you do that well, you’ll do really great in a slightly cushy sticky saddle on an autopilot warmblood on manicured footing. The person who struggles is not going to find a winning round in a can.
And when you get old, some of the “cheats” are a way to keep riding without being a cripple. There comes a time when being GM perfect hurts. And you realize that short stirrups and heels down is ripping your back up. So you lengthen the stirrups, invest in full seats, get a cushy saddle, a smooth horse, a can of sporti-haft spray and merrily continue to enjoy the sport… without needing a bottle of perscription pain killers at the end of the day.
