I don't have a strong opinion on whether we "bless" that or not, and say
that we should just use 1, 2 etc. going forward or not.

But I do think that us doing so initially wasn't intentional, and has
been in opposition to a strongly worded claim in a comment in hash.h
(which I modified in my earlier related RFC series).

So maybe not part of this series, but it seems prudent if you feel
strongly about using this for new formats over what hash.h is currently
recommending that we have some patch sooner than later to update it
accordingly.
