Any use case that needs /dev/sev-guest, I guess. Saves software from
having to do the modprobe manually. For example, nothing I can find in
https://github.com/AMDESE/sev-guest loads the driver, it expects
/dev/sev-guest to be there already

Mostly I assumed lack of autoloading was an oversight. Was it
intentionally omitted?

Thanks,
