I totally agree - except when it comes to defaulting to square pixels, 
which /does/ make sense nowadays; after all, that's what any reasonable 
image handling software defaults to as well if the input image material 
provides no embedded resolution information.

(Um... that looks more like 8K to me... or am I missing something?)

It might be worth noting that of all those aspect ratios, 16:10 is 
closest to the famous Golden Ratio (1.618...:1), which has been 
considered an aesthetically superior ratio for literally thousands of years.
