You're absolutly right. But as for me, I prefer to made interface as simple as possible. On mobile autorotation is necessary 'cos they're limited both in screen size and number of hard keys. On edge we allready have both: the large display, and additional buttons to rotate the screen.

p.s. at first EE must to fix an bug which case to some apps running in default (horisontal) mode instead of current (vertical) mode. Allmost all photo\video apps has this bug.
p.p.s. and fix some apps running in small screen, which also takes a few lines of code to fix.
