I would have thought that's how all fixtures are hung ? Over here in ireland most heavy pendent fixtures are fitted that way. Particularly heavy glass/brass ones.
Normal cheap n' cheerful lampshades attach to the usual bulb holder ring and other lamps use various combinations of screws to hold them into the ceiling.
As for ceilng roses, they're not always used. Often a a choc block in a chocbox in the ceiling behind the fitting is all that's required but it's not unusual to simply have 2 cables coming to the back of the fitting and joining them with a strip connector.
Lighting is almost always individual cables here.
