Still the same.

Aside from it being X11 behavior, why do you consider it the "right"
one? I see how I could use one monitor's dimensions (to make Emacs take
full screen, or half width, etc), but what use is the "total size"?

My monitors are of different size, you couldn't make Emacs fully
maximized to both of them, even if you tried.
