Only slightly joking but the solution is for supers to lie like hell, i.e., tell members/golfers they are 11, when they are really just 9.5, as if any could know the difference. Since there may be a few who challenge them, they may need to adjust their stimp meters so a demo will yield the "correct" numbers. Or, if the golfers really aren't that familiar with the method, just measure downhill slopes to get a better result.
Trust me, it is done a lot, but perhaps could be done a lot more.
As to drought tolerant grasses, I have no idea what is being researched, but generally have found the current drought tolerant grasses to be a bit wider bladed than others. If the first line of defense is choosing grasses by drought tolerance over playing quality, then there may be a lesser quality. Although, those turf researchers will probably come up with something that plays well enough for about 98% of us.
