Looking at FNV it is simple enough that a complete specification of a 64 bit
FNV calculation could be included in the document.

It does have the advantage of removing the whole agility and hash
negotiation issue which is a good thing.

However, is it possible to unite all wills here?

Who would object if we select FNV hash instead of a cryptographic hash
function?
