This just changed for me... but the hardware may matter, as I'm on Hades Canyon, using the amd gpu, not HD graphics.
A few days ago I updated to the then-latest 4.19-rc2
(and wrote https://ubuntuforums.org/showthread.php?t=2400400 documenting
exactly what I did).
Using plain old X (no desktop) on my Hades Canyon, I now see a 16384 x 16384 limit:
$ xrandr
Screen 0: minimum 320 x 200, current 11520 x 2160, maximum 16384 x 16384
Three screens horizontally work.

I have not yet tested on HD graphics with the new kernel.
