Hi, that is good news.

It seems that our boot loader will fail to boot after zpool upgrade. Is
that a known issue?

I've replicated my setup, root zfs over GELI, in a VM to avoid any surprise
(phew!), and it booted fine after upgrading the system. Although it fails
after zpool upgrade (yes, I know you've asked us to be cautious with zpool
upgrade):

ZFS: unsupported feature: org.freebsd:zstd_compress
ZFS: pool zroot is not supported
ZFS: can't find pool by guid

Thank you!
