My argument concerning performance is that for long messages SipHash
isn't actually significantly faster than (possibly round reduced) MD5,
Skein, Blake2 etc.

The main selling point of SipHash is that it's faster than normal
crypto hashes for short messages. Since ZFS almost always hashes long
messages,
the advantage of SipHash doesn't matter.
