Thanks for the resources! As for a sane way to upgrade from SHA256, the first two bytes specify what hash they are using: "the first two bytes in hex is 1220, where 12 denotes that this is the SHA256 hash function and 20 is the length of the hash in bytes ― 32 bytes." I'm guessing they included that so that the hash could be changed at some point. That's just my guess though.
