Seems interesting, fast, smart people behind it.

I probably wouldn't use new fast symmetric crypto for anything
important until it's been analyzed for several more years.

(Maybe you can argue that the NORX/BLAKE2b/BLAKE2/ChaCha/Salsa
analysis applies, but I dunno, it's only using 4 rounds of BLAKE2b, so
it's not obvious to me how much analysis it inherits).

But it would be fun to experiment with, totally support you naming and
spec'ing this, linking a doc on the Wiki, etc.
