Wayland has a proper protocol for fractional per-output scaling: https://wayland-book.com/surfaces-in-depth/hidpi.html https://wayland-book.com/surfaces-in-depth/hidpi.html. While there are many reasons why I prefer Wayland over X, this is the biggest. X only allows setting a DPI per "display", but not per screen (multiple monitor setups where you can drag windows between screens use one X "display"). So you have to resort to these hacks.
