Would you have paid extra at the time for him to fix the screw?

Stud mount wheels generally don't have retaining screws and work just fine.

There are a couple of other reasons why bolt attached wheels have a retaining screw.

1 It keeps index of the rotor holes and hub holes when the wheel is off.

2 A flake of rust "could" fall between the hub and rotor causing a braking vibration but , again , stud mount wheels survive just fine. ( Brake vibration is caused by a thickness variation more than it is caused by a wobbly rotor. )

Wheels corrode to the hub index and not to the face of the hub so the rotor coming off with the wheel won't be an issue. The caliper will prevent losing the rotor during a wheel change.
