I remember so odd not so transparent stuff not working well when I tried it years ago, like throttling of cpu/gpu, fan control, sleep modes, stuff like that. Provided your hardware is fully supported though I think they provide an excellent experience.
Maybe I should try to rebase my home server to freebsd …
Installing things on fedora atomic spins is hardly tinkering more than necessary. You either layer the package, install it in a distrobox, use something like homebrew that installs packages outside of /usr, use app images, nix package manager, docker/podman or a flatpak.
These things exist for a reason, because they complement many distros that would be otherwise lacking. They can add a new app to a stable Debian, a stable dev environment to a bleeding edge arch, an isolated environment to use a untrusted app. If you use Linux these days you should be aware of these distribution agnostic options, or you will have issues understanding what is even going on and limit yourself unnecessarily.
