Hi,

I have unassigned myself from the tickets and will no longer pursue the
addition of new crypto hash algorithms. I might try again when blake2
and sha3 are more widely adopted and the opposition from other core
contributors has diminished. Acceptance is simply not high enough to be
worth the trouble.

Kind regards,
Christian
