I think there should just be a font and border standard that is easily isolated and orc'd. That would make the human readable url and the device scannable URL one in the the same.
But I realized something about QR codes. Though they can contain any text, the vast majority of the time they're URLs. But they're not just base URLs. They contain query variables that people couldn't be bothered to type in, but which let the advertiser know which exact code (or which print run at least) was scanned.
