It is a wonderful resource, but doesn't solve all trouble. It specifically says that the only modern DE that supports hidpi scaling well is KDE. Gnome hidpi support is crap (no fractional scaling), Unity is going away. Sway and the rest are of course cool, but most people use some kind of GUI toolkit like GTK that either supports hidpi or not (mostly not well).
