Oh yeah. From messing around with Fedora Atomic, I can definitely see something like that working for a lot of people - no messing around with system libraries, stuff installs in a click, if it’s not available as a flatpak you can find an AppImage, etc. Immutability is really convenient if you just want a system that runs and can revert back to a working state easily without fiddlefucking with the terminal/fighting Google to get the info from StackExchange threads.
