Renderer default aspect ratio

how about a future where all renderers have an initial aspect ratio of 1:1 ?

i am not a big fan of apple but i think the square option in os7’s camera software is a hint towards my point, that square is the new 4:3, as there are so many display mediums nowadays (i know they did it for istagram optimisation but the point is the same)
