I care more about vertical resolution, and vertical height, more than about aspect ratio. So with 3k and 4k getting more popular on higher end laptops, the 16:9 doesn't bother me as much. I can keep a code window on one side and documentation (or program output) on the other side of the screen. The only other drawback of 16:9 is that in order to get an acceptable height, it makes the laptop too wide. My solution is to use clip-on reading glasses over my regular distance prescription, when using a high res laptop screen.
