If the panel accepts the Argon2 tweaks, it should give the other finalists
a decent amount of time to propose tweaks as well. Everything else would
be extremely unfair.
I wouldn't mind that. But the consequence is clear: This would delay the
process by a couple of months. Just waiting to the end of this mongth
won't do.

That sounds like an optimisation to me.
BTW, Catena has very specifically been defined as a framework. You are
invited to plug in the hash function you like -- including SHA-512,
BlaMka, and whatever. (The default instantiation is based on Blake2b, but
that is just one of many allowed instantiations.)
> What about a change in block indexing during memory filling?
This is something I would consider a tweak, not an optimization any more.
So long
