However I wouldn't want people renting my aeroplanes and doing it in a 172!
Nor I, they'd never do it again. Two reasons, one, they'd never ever get to fly my aircraft again, two, they'd probably never ever be able to sit down again as my size 10 steel toe cap would be firmly embedded where the sun doesn't shine.
That said I don't see a problem with anyone wanting to do it in their own aircraft. They know their aircraft and they know the risk.
