Interesting unintended consequences with this - my sister-in-law had her job hours radically shifted to deal with this rule - and not in a good way that she appreciated.
I suspect if the overtime rule sticks around we'll see similar measures pop up for it.
(I've also known one or two places where they flat out told people to not report hours above a threshold and/or "mysteriously" deleted the overtime from the hours recorded, and the employees felt they couldn't report it to external authorities without getting fired.)
