Appreciate it. As someone who basically continues to use ZFS happily and didn't kick the tires because of the stability & ergonomics issues in the past, this is concerning to hear...
Looks like kicking the tires will remain somewhat in the future for me.
It's much stable after 6.4 kernel. Last year was not really stable yet.
I faced too, problem is I didn't know we have to schedule a `btrfs scrub`. After kernel update and scrub, everything works smooth.
