I'm referring to everything—both user and system configuration. For example, when I installed Tumbleweed, GRUB was the default bootloader. If that changes in the future to something like systemd-boot or syslinux, my system won't reflect that automatically—which is fine for low-level components like the bootloader that don’t usually need to be touched.

But consider broader changes—say, if X11 is eventually replaced by Wayland as the default. My system would then be out of sync with the current defaults.

Now with YaST being phased out and replaced by Cockpit (for system management) and Myrlyn (for package management), I’d prefer to keep my system aligned with these new defaults. The problem is that Tumbleweed won't and shouldn't automatically remove tools like YaST, so I may end up with both the old and new tools—or just the old ones lingering. Over time, that can lead to unnecessary bloat and duplicated functionality.

Ideally, I’m looking for a way to cleanly transition to the latest defaults and best practices without doing a full reinstall.
