Unnecessary for you... my screen are 1920x1200, I would need 16:10.

Changing the default right vector (even to something like
image_width:image_height ratio, assuming square pixel everywhere)
would only have one sure effect: break every historical scenes.
Without providing 100% satisfaction to all users. Better not move.

And guess what: 4K screens are coming... and there is at least 5
different resolution under the name 4K, none with exactly the same ratio
.

So far:

 * 4096 x 2160 ( 256:135) [DCI native]
 * 3840 x 2160 ( 16:9 ) [UHD-1]
 * 5120 x 2160 ( 21:9 ) [UWT]
 * 5120 x 3200 ( 16:10 ) [WHXGA]
 * 4096 x 1716 ( 2.39: 1 ) [DCI cinemascope cropped]
 * 3996 x 2160 ( 1.85: 1 ) [DCI flat cropped]
