Maybe I'm weird, but the 2x scaling on my Framework looks fine to me; not cartoonish. Xfce requires a few manual settings to get it right (which did frustrate me for the first week), while GNOME and Cinnamon appear to handle it well by default.
2x scaling on a display that needs 1.5x scaling would look cartoonish. Every GUI element — titlebars, headers, icons, menus etc would be bigger than they should be.
You could scale down the fonts to make the text bearable and not look like it was written for advertisement banners but then you've basically got a weird and broken setup that would be impossible to use with an external monitor or any other display.
