Huge PITA. Do they even support raspberry pi hats? If yes that's another $25, plus now it blocks your fan unless you get the proprietary sideways fan hat. It also won't mount into any cheap cases anymore. This means it goes from "hey I can buy this for $70, throw into a case with 128gb nvme and run stuff" to "ok so $70 + $25 hat + different fan hat + $40 to get taller clearances"
