Yes, except most people wind up looking at the leftmost third of the screen the vast majority of the time (see visual heat map research) which results in chronically bad posture with very wide screens.
I use a window manager to split a 21:9 5k2k monitor into 11:13:11 panels, so the largest is in the middle. Suits me just fine, and I mostly look at the middle panel, with terminals and browsers off to the left and right respectively.
Yeah, not advocating for big wide screens, either. A 17x17 square display would be pretty sweet. You can achieve this by setting the right mode on a 27-inch widescreen, because they are 17 inches tall.
