> fractional scaling does not render the desktop at a higher resolution
than your screen

Xorg fractional scaling DOES render the desktop internally at higher
resolution than the monitor, and then downscales it to the physical
monitor. That's how you get a "fraction". For example:

  Monitor = 3840x2160
  Scale = 150%
  Render resolution = 5120x2880
  Transform matrix scale factor = 1.333
  Final visible resolution = 5120x2800 / 1.333 = 3840x2160

You can confirm this by looking at the details in 'xrandr --verbose'.

> If one could simply choose different integer scaling for different
monitors that would solve 90% of people's problems.

Yes you can already but only in Wayland sessions. Xorg sessions are
limited by Xorg itself not treating each monitor as a separate
framebuffer.
