To be clear: having the networks that make up the internet agree to depeer networks that don't implement a protocol is roughly the same as "making it a requirement", and the petitioning you'd need to do is "convince all the networks to agree to do it". Because the internet is "free", more or less, there isn't much in the way of enforcement of which RFCs and practices must be followed to be part of it, which is a big part of the reason that BCP38 is so underutilized today.
