I think that's fine, and I am adopting the same view for SRFI 125/128.
I add a warning that if you expect your hash functions to interoperate
with the reference implementation of SRFI 69, you should write them to
accept and ignore a second argument.

At the moment, however, I am still sticking to the requirement for
non-negativity, since it is in both SRFI 69 and R5RS, even if it is
not necessary.
