The old adage is never use v x.0 of anything, which I’d expect to go double for data integrity. Is there any particular reason ZFS gets a pass here (speaking as someone who really wants this feature). TrueNAS isn’t merging it for a couple of months yet, I believe.

Also relevant, The Plot Against America which puts it in a philosophical / idealogical context. Their actions now make (an awful) sense to me.
