Yeah. I suppose this functionality isn't everyone's cup of tea. The cool thing about Wayland though is somehow it makes the windows still look crisp and good while making them the same size. With the canonical hack to xorg, they always looked blurry and gross. The gnome wiki had this to say on it:

"On a Wayland display server, each connected monitor will have a scale that depends on the DPI. A scale affects the scale clients draw surface contents when they are visible on said monitor."

So it seems like it actually modifies the drawing at the application level rather than rescaling it like an image.
