You can do the same from an USI made from mkosi (mainstream distros support) with kernel boot parameter systemd.volatile=overlay. https://github.com/rhee876527/UKIfy-Xubuntu

This looks interesting. I just set up an Alpine Diskless system that boots from a USB stick.
I originally tried to set up a NixOS diskless system with persistence for the same reason as the author but the LLM jerked me around and I had little understanding of the implications of the commands I was using. So I thought it best to pull the plug on that and stick with something more familiar.

If you already have a ZFS pool, I'd probably personally just throw on zfsbootmenu and a ZFS-root Alpine install. But, this is cooler and does have advantages:)

TIL about ZFSBootMenu! Still, the whole frood system is significantly less complex than ZFSBootMenu alone.

What are the _obvious_ reasons for the NAS root to have an SSH key?

To log in and administer it? There's even an example; search for "extlinux --once". (There are other options, like a web UI or non-root SSH, but that's the obvious thing. Also if you want to advocate non-root I'm going to want to hear a threat model.)

You don't need a private key on the host for that, only your public key in authorized_keys.
Edit: Oh boy I should have paid more attention. Those are the host keys. :facepalm:
