The problem with that is most major distros market themselves as "new user" distros to some extent though. Noob-friendly, out-of-the-box, easy, etc are all distro-marketing buzz-words that mean nothing.

You can't expect them to only use Wayland, Pipewire, Systemd, and Flatpaks because that dream requires every distro to use Wayland, Pipewire, Systemd, and Flatpaks, which will never be reality.

Most distros will probably eventually adopt these tools, but there won't be a sudden shift. It will be gradual.
