Yes, I really love the Silverblue download in the background, reboot and you are up to date updates. So much better than watching the package manager do its thing. :-)
I don’t know about your knowledge about Ansible, and when you are already running Silverblue and are happy with it, it might be more worthwhile for you to explore how to automate Silverblue and the containers you are using… and write a blog post for people like me, how you did it, so I can learn. :-P
Ansible… basically it allows you to install software with the package managers (apt, dnf, …), configure/restart etc. services, clone git repositories, run arbitrary commands, configure stuff with dconf.
Example for my workflow:
When Debian 12 got into the alpha stage, I simply set up a virtual machine, install git, ansible and vim, and then I start from a known starting place (like Gnome Desktop for desktops, minimal for servers). First, I clone my git repository with my dotfiles, and link all the relevant dotfiles. After that I simply use Ansible to install all packages I will use from that distribution, run dconf to configure Gnome for my needs, configure/download software from 3rd party package repositories or just download tarballs and install them to /opt or ~/opt. Of course also flatpaks can be configured/downloaded via Ansible.
Once, everything works great in the virtual machine I will work in the VM for a few days or even weeks. If everything works stable I’ll just make a clean install of the operating system, add some hardware specific tweaks (change grub config, tweak WIFI drivers power mode) and then I am up and running. Thanks to Debian, my Ansible configs are mostly stable with minor tweaks for around 2 years, and when time is due for Debian 13, I’ll repeat the cycle.
The way I do things with Ansible have grown for a long time and are tailored to my private/professional use cases. I simply like having the same setup on every desktop/server I deploy, because I never have to wonder, if my software is configured in the way I like it, if a hotkey works or if something I use is installed or not. (And if my hardware dies or I do an SSD upgrade, I am up and running within minutes, same is true if I get new hardware.)
Still, it is a tradeoff. I really like Fedora, but one year of updates is too short for me and my initial investment to setup a new version of Debian. Further, I only use dconf based desktops like Mate or Gnome, because I can simply configure them painless 100% via Ansible. OTOH I have MY Debian desktop setup running on multiple AMD64 and AARCH64 physical and virtual machines. If I want to experiment with software, I just create a VM, start Ansible, get a cup of tea and I have a disposable machine to play around. Further I have my setup 100% documented, if I wonder, what strange power settings tweak I needed in which file to make Debian 11 work on my netbook, I know were to find the 100% correct answer…
Excuse the wall of text, hope that gave you an idea, don’t hesitate to reach out if any questions are left. Obviously, you have to decide for yourself if such a setup is worthwhile for you. In case you use only one Desktop, this would be total overkill. :-P
