Yup, but I still have graphics start on a tty ;) I just don't have a login because I use an ephemeral OS (custom alpine base) with runit. It's like windows 95 all over again, you start the computer and that's it, use it. Highly recommended, no passwords just yubikeys
Love Tails, but I haven't used it in ten years. I have had Tails and Qubes disposable VMs on my mind though.
I switched off of Qubes last year to my own Alpine chroot with a hand crafted kernel and initrd that lives only in memory. I find turning off the computer when I'm finished and having it forget everything to be a very peaceful way to compute. I owe the internet a write up.
I feel like ramfs for root filesystems is an underused pattern more broadly. "Want to upgrade? Just reboot. Fallback? Pick a different root squashfs in the grub menu"
