I've been playing with Omarchy ("highly opinionated" Arch configuration) which has full disk encryption, and was wondering if I could use it as my primary VM. While in person, I would get a full GPU accelerated desktop, with access to all the long-running compute jobs etc. that I'm doing otherwise.

However the one thing stopping me is exactly what's solved here with the new MacOS. If I'm away for a few weeks, and the machine power cycles, the full disk encryption password still needs to be entered, in person, as far as I can tell. I'm running it under ProxMox, with the GPU in-person USB devices being passed to the VM. So the standard VNC viewer doesn't work for the setup.

It would be interesting to see if Omarchy tries somethnig similar...
