I think I've seen a couple of mentions of bcachefs and it seemed interesting at that time, but I completely missed the point at which it transitioned from "a cool prototype" to "production-ready, stable and mature". Is it already? Perhaps it needs a PR department of sorts, because it sounds really amazing ;)

You haven't missed it--that point is still in the future. Subvols on bcachefs are only a few months old, and much closer to the "cool prototype" end of the spectrum than the other end. My last test run of bcachefs ended after 29 minutes with a readonly splat from the 'cp' command.

Speaking of cool-but-unreleased filesystems, has anyone heard from Tux3 lately? It was showing some mythical benchmark numbers where an in-memory loopback was outperforming tmpfs, then it fell off the face of the earth.

The mailing list has had nothing but "is this project alive?" type messages for the last couple of years. The latest one of those to get an answer was last year:

I'd say the last time it looked even vaguely healthy was 2014, and even that was after a couple of very light years, so I think it is probably never going to see the light of day, sadly.
