Except the code will be open so if Canonical doesn't make it configurable, other people can, and if they do it right without introducing unneeded complexity, their patches might just make it upstream (Ubuntu).

This is assuming of course that people who like to fiddle with their display will stay with Ubuntu.

Not many people like to do that anyway. But if there are people who want that kind of control, it's not impossible.
