I don't especially want a single tall, thin window for code. 5:4 is still wider than it is tall. My usual development environment is Emacs with two panes (Emacs calls them windows for historical reasons) side by side on 4:3.
My thinking is that a screen that's close to square works better for a wider range of tasks than one that's very oblong. A rotating oblong screen that could be tall or wide might work nicely for a lot of situations too, but it would be hard to implement well on a laptop.
