Except that the hardware doesn’t necessarily offer perfect integer scaling. Oftentimes, it only provides blurry interpolation that looks less sharp than a corresponding native-resolution display.
The monitor may or may not offer perfect scaling, but at least on Windows the GPU drivers can do it on their side so the monitor receives a native resolution signal that's already pixel doubled correctly.
Most modern games already have built-in scaling options. You can set the game to run at your screen’s native resolution but have it do the rendering at a different scale factor. Good games can even render the HUD at native resolution and the graphics at a scaled resolution.
Games are not what I had in mind. Last time I checked, most graphics drivers didn’t support true integer scaling (i.e. nearest-neighbor, no interpolation).

Modern OSes also scale fine.
It’s really not an issue.
