It's not a simple "promotion" but breaking compatibility with the
existing protocol - it's on the list of things to fix if we ever
get around to a major compatibility breaking revision:

Several?  I've yet to see many common monitors larger than 2560 pixels,
so that's still 14 screens wide/high.

Of course.   We are capable of basic math.
