OP doesn't have any evidence that any valet he uses drives his car too far. Just an article he read about this having occurred.

As to resetting the seat, that may be a safety necessity depending on relative height and leg length of OP and the individual valet employee.

One could spend a fortune on this exercise or one could simply reset the seat (or program one's comfortable position if the vehicle has that feature), quickly check the air vents and be off.

Or just don't use valet.
