Anyone who has used any Linux knows HiDPI or mixed DPI monitors are a massive issue on Linux. Even when you get your xrandr configured perfectly fine, disconnecting is a hassle. And that's completely ignoring apps, QT, GTK, etc all handle DPI differently. So you need a different config with DPI setting on each.
One of the best I've used is PopOS with the HiDPI daemon enabled. But even that has issues.
Even Windows can't deal properly with having a 4k laptop screen and a 2k monitor attached. Have to deal with weird text scaling issues and other weird scaling issues.

But MacOS can and does it beautifully.
