Didn't really look into NixOS so only learned that it is an immutable OS after reading your article.
I once tried Fedora Sericea. Ended up having many Toolboxes (like Distrobox) with libraries and tools for development, but only a couple of Flatpaks.
I think the ideal user for immutable OS will be someone who want to use computer like a smartphone, just install apps (as Flatpaks) and let the OS do its update things.
