Yes because you can always do a dusaster recovery by reinstalling and restoring data.

A reboot doesn't break anything. Bugs do.

Any time I had a regression after a kernel update on a linux distro I could boot it on a prior version from the grub menu. Any time I had a regression with a software package I could rollback to a prior version. Rolling back updates is a problem that has been solved for decades, at least on linux systems.

The key with unattended upgrade is you want to have decent monitoring to make sure you never run out of disc space and do not figure it out weeks later if you have had an issue.
