Cool. Any benchmarks? For settings like 2 MB RAM + e.g. 1 GB ROM, and
for larger ROM. On GPU, does the ROM currently have to fit in one
global memory allocation?

OK.

This is now mostly wasted effort, but I hope it was good experience.
It isn't impossible that someone will use a non-selected PHC finalist
somewhere, though.

These are very useful and are almost like I wanted them to be.

As a higher priority, please re-do the Lyra2 vs. yescrypt benchmarks
with the slight changes I suggested: m=64 vs. r=6, and m=80 vs. r=8.
We'll share them with the PHC discussions list then.
Working on Argon2 is fine. At least you need to familiarize yourself
with it. You should simply be aware that it's a moving target. It's
helpful to have some preliminary results for it, and you'd need to be
merging tweaks to it and re-doing benchmarks later.
