Are you aware of any mixing protocol anywhere that is sufficient with just one round?

the whole point of a proper Zerolink implementation is there's no way to know which input matches which output.
even after a single mix.
as I understand it, Wasabi didnt end up implementing it completely, but Whirlpool did (with modifications).
this is not to shit on JM, just that people know the tradeoffs.
you can get reasonable privacy with JM.
probably.
its all a probability game.
