Man, I really want bcachefs to do well; it's so nice, and while I'm happy with btrfs, I would really like to be able to have more RAID options in it.
Years ago, I used to do the LVM + FS dance, but after a couple of incidents I discovered it's a kind of jenga tower that's difficult to rebuild of things go really caterwumpus. Since then, I avoid LVM and have been waiting for stable RAID5/6 support in btrfs, but have come to the conclusion that it may never arrive; it seems to be either not a priority, or impossible (or exceedingly difficulty), because the years creep by with no apparent progress and the RAID warning increasingly looks as if it's written in stone.
So bcachefs is really interesting to me. But I'm getting Hans Reiser vibes from Overstreet; what is it with filesystem developers and oversized egos?
