As I grew really uncomfortable with having a decision that seems to be
based on hunches by non-experts (we rejected the preference of the only
cryptographer who weighed in, after all, precisely like we did over a
decade ago), I asked whether I could loop in one of our in-house experts
with this public discussion.

Y'all should be quite familiar with his work: Dan Shumow.

Dan, thank you for agreeing to chime in publicly.

Ciao,
Dscho
