I don't think you're correct, immutability is great for long-term maintenance and makes everything, especially updating, much easier for new people.
Non-immutable distros will often have conflicts, or when a dist upgrade happens, issues occur, immutable distros largely sidestep those issues, and I believe kinoite is the simplest, most reliable option for someone unfamiliar with performing these upgrades.
The moment there's a dependency issue or conflict, they will have problems.
Fedora is not a flavor of the month project, it has just as much history as mint/ubuntu, and there's a reason they're shifting to atomic. Furthermore wayland is better for the vast majority of people right now, imagine you bother to switch to the linux desktop and then in a few months everything completely changes because wayland happened, it'll look like linux is absolutely insane from the perspective of someone who hasn't immersed themselves into the nature of this transition.
