For paranoid people, like me, at the level of users when setting up new
systems, would it be beneficial to do "zpool create ... -o
feature@block_cloning=3Ddisabled" ? Does that provide any benefit over the =
sysctl
you mentioned?

Separately (And I apologize if this is not relevant in this bug report), any
thoughts as to whether #15533 ( https://github.com/openzfs/zfs/issues/15533=
 ),
which I got hit by on Linux when running on top of LUKS, is in any way
applicable on FreeBSD when running ZFS on top of GELI? I ask since OpenZFS
commit bd7a02c was, as far as I can see, not Linux specific and I have a few
clients with GELI+ZFS setups. I did notice your vdev_disk rewrite is Linux
specific, so I was just curious as to what the situation might be for FreeB=
SD?
