For example, suppose a compositor has a maximize policy where it can "maximize" a window to take up the top-left 25% of the screen. This size could be too small for the application, yet it falls within your non-interactive resize case. > > > It seems like continuing to add size hints based on this logic is almost > > guaranteed, especially if you then add in the point of tiling > > policies--surely handling tiling would be made even easier by adding > > min/step/aspect sizes! > > > > To me, xdg-shell should just be a bare minimum of things required to > > implement a UI with Wayland.

Adding any form of size hints is a slipper slope which leads to more size hints imo.
