No scoring, no runout! Leave 'em alone, they will work just fine, and yes it is an industry wide practice mostly for CYA especially on disc brakes. With hard to come by parts I like to leave as much material there as I can. Hence no machining unless needed to correct a problem.

I had my shop look at the brakes on my '65 and it's getting to be time for a new set of brake shoes and we noticed one leaky wheel cylinder. The mechanics insisted that the drums should go to the machine shop for resurfacing. Not because they're out of round (that we can tell) or scored (that we can see), but because the drum we were looking at had a mirror-smooth shiny surface which he said was too smooth. I'm not sure if he meant just too smooth or that the first few thousanths had been hardened so the new linings wouldn't wear in properly. I've had the brakes done on this car probably two or three times since I've had it an have always avoided having the drums turned in order to preserve their thickness. A measurement showed that this drum has enough material to turn. At any rate, this is a very old-school shop that I've used for minor things and they have been good to my car. I just get the idea that drum-turning is standard practice for them.
