Comment 3 for bug 1872124

I don't think that implementing just subiquity is enough. Ubiquity was the last piece of ubuntu-drivers integration on the Desktop, as update-manager continiously was already checking for any new drivers that are available for the systems' hardware, and continiously providing notifications to install / switch between new alternatives / dismiss installing drivers, on continuous basis post-install / post-upgrade. Doing this during install, simply moved that step from post-install to pre-install.

Ubuntu Server currently does not have ubuntu-drivers integration with motd, unattanded upgrades, and apt output to notify users of the newly available driver implementations, and how to opt into them.

Command line tooling exists, but currently only used non-interactively by cloud-init on some compatible public clouds.
