Well, we implemented 20 rounds and not yet 12 rounds.

In how far is eSTREAM relevant; why do we need to care about it?

Is there any project already using Salsa20r12 or is there still time to
ignore this variant?  In other words, would you mind to change your I-D
to “Standard” 20 rounds Salsa?

It is not that I am against adding this variant, but I try to keep the
number of implemented algorithms low.  We already had to add a couple of
algorithms simply for political reasons.  I would appreciate if we could
avoid that (and thus make IanG happy).


Shalom-Salam,
