I tested a daily install of Ubuntu 20.04 from 20220131 and no packages are suggested for autoremoval and ubuntu-restricted-addons was installed after the reboot. However, I didn't test with nvidia hardware so its possible the bug in the original description still exists.
Additionally, Steve's point about this needing fixing in ubuntu-release-upgrader might still apply in that systems that install from Ubuntu 20.04.3 media may have had packages autoremoved that should not have been.
