I think it's the faucet threads that are the concern, not those of the hose. The anti backflow piece that's been required on outside faucets have a set screw that rusts/corrodes and cannot be removed and then the backflow piece with the setscrew galls the faucet's threads when coming off the faucet, which is necessary to repair or replace the useless backflow device, after time.
