And I would add that the fact that often multi monitors have heterogeneous setup where resolution/dpi and zoom level may differ between the monitors (different brands/model or spanning from laptop screen to monitor) therefore it makes even harder to span across screen in a reliable fashion. Window managers struggle today with that, just drag a window from one screen to another and see how it gets redrawn and layout again if the monitor configuration differs. When the window spans across two "different" screens they also look weird and "zoomed in" (see my picture) : on my main screen it doesn't look right for e.g. (and it seems that they're are some decision in the WM on when to pick a given state, often based on how much the window is spanning on a given screen).

In the illustration of @zouhir it will be hard to align the right yellow piece (even if it was full screen) to the left yellow piece, so it may make the content look weird unless the author purposely create a split UX (not to mention the physical aspect of it). 

I think at the end we're opening a can of worms by enabling this on multi monitor setup. And the fact that multi monitors have been around for decades and nobody asked for features like this (aka spanning on multi monitor) is also a strong indicator that maybe we don't need that.

I would like to point out this btw which somewhat try to address multi monitor and window placement : https://github.com/webscreens/window-placement/blob/master/EXPLAINER.md
