Quad menu is one of those UI elements whose graphical style haven't been brought up to date. My wild guess for that is that Max users don't rely so much on it as the Maya users do on their Marking menus or Blender ones on their Pies menus. I don't use it either that much but this doesn't mean it shouldn't get a proper attention and have a style adequate to 2020. This is different than having different or extra functionalities and for this there are already a couple of suggestions out there. Therefore, this is just about the look.

The new menu style introduced with the new modifiers could also represent a small starting point to bring the quad menu to 2020's.

Among the places to possibly draw inspiration for a possible new style are the 3ds Max Caddy Controls and why not the Maya Marking menus.
