I agree completely with puffmugs. Almost all water stub outs are done is copper and compression stops installed after sheetrock, paint, etc. You rarely see soldered stops these days, at least not from plumbers, and you really never see threaded stub outs for exactly the reason you mentioned. So, to sum up, stub out copper, and use compression stops. Cant go wrong with this method, and dont have to worry about burning anything with the soldered stops. Aslo, it is much easier to replace a compression stop vs a soldered stop in the event it ever needs to be replaced.
