From what you describe we actually strongly agree. This stuff should work and be invisible to the user. I just meant that the environment should expose the DPI details to the programmer and not pretend everything is low dpi like it's always been.

Wayland is about a bunch of amateur programmers learning for the first time how graphics work, individually and separately all in parallel. Wayland needed to have a bigger, definitive core library designed by experienced developers. What we've got now instead is a myriad of low-level graphics implementations, none of which handle edge cases very well.
