Thx for the elaboration. That's what I roughly meant with "image centric os".

Opensuse aeon encourages you to use flatpak. The first thing it does right after installation is to install apps from flathub, including firefox (unlike silverblue).

An example from the doc

For this reason, All Applications, Browsers, Codecs needed for specific apps, etc are provided by FlatPaks from FlatHub.

Especially the following

To reiterate: EVERYTHING should be done via Flatpaks or be installed in a Distrobox if a package is not available as a flatpak. Using transactional-update is strictly what you need for your host operating system to work (exotic drivers, specialized vpn services).

Usually, you do not rollback, you do not go back to an older system. On both systems, you use distrobox and flatpak. I don't see much of a difference as an end user.
