PS
I posted the previous post because I'm sure some merchants want to do something now, but lack the full details on how to do it.

I don't think there needs to be an established universal 'right' and 'wrong' code for merchants to implement their own policing on their own terms. They just need the knowledge on how overwriting happens at the moment. Then they can at least decide how they want to run their program.
