> Well, why can't distributions that come with recommended GUIs just set that high-than-normal priority by default?

Feel free to file bugs for your preferred distro. It would be especially appropriate to do this for critical UI processes like xorg/wayland or lightdm, and for "lightweight" desktops like xfce/lxde that aren't going to cause resource pressure under foreseeable conditions, even when run at higher-than-normal priority.
