Is it giving more vertical space, or taking away horizontal space? A 16:9 screen would be fine if it had the same vertical resolution as the 3:2 screens. In that case you work off the center of the screen and put various gadget items to either side. Or for the larger screen laptops that include a number keypad, put your workspace on the left 80% and things like your Slack / chat and email notifications on the right side.
Actually come to think of it, a perfect window manager would be something that allows for overlapping windows in the central region, and lets you have adjustable left/right regions as tiling window areas. Combined with something that can tell an application which region it is in, so it can adjust the interface (optionally) to fit that region's purpose and limitations.
