Mike,

Thanks. The authors of the Argon2 design may in due course tweak their
design to avoid the identified problems, or argue that they are not
sufficiently worrisome to warrant a change to the design.

We definitely need to factor this in to our deliberations, and we will
take the time to do so. Let's see how it plays out...

Regards

Kenny
