Kubuntu 25.04 here, root on OpenZFS thanks to the installer for Ubuntu.
How is OpenZFS second class on Linux?
<https://github.com/openzfs/zfs/> is not perceptibly FreeBSD-first.

While You can spend some hours installing Linux with ZFSBootMenu and LUKS encrypted Root on ZFS - there are ZERO Linux distributions that allow ZFS Boot Environments out of the box.
That is the reason 'why' Linux is not the first class ZFS citizen.
There is also the ZFSBootMenu part ...
If you have done this at least once - noted the commands, etc. - it will take shorter - but never shorter then FreeBSD 'Auto (ZFS)' option in the bsdinstall(8) installer where you just select the disk on which it needs to happen and hit [ENTER] key.
Reminder: I neither want, nor need, to check several different guides that cover only the encryption part.
In any case, I'll take additional advice; it's impossible to trust apparently authoritative statements from you.
I'm considering alternatives. Not ZFSBootMenu in isolation. I'm in no rush.
Ahh now i get the point why you have no problems destroy your system with a simple pkg command ;)
