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"
