 Replying to [ticket:43524 azaozz]:
 > One problem is that we don't have a 2x images for the built-in `large`
 size. Currently when displaying images larger than 512 px on the front-end
 on devices with high pixel density screens, the browser has only one
 choice: to output the full size/original image. These images are often as
 large as 6000px x 4000px and 4MB or even larger.

 Sorry for being rude, but please support your claim with actual evidence.
 Out of every image on a website, it seems unlikely to me that most of them
 are over 4 MiB.

 > To fix this and not output needlessly large images we need a new size
 that should be 2x the current "large" size, max 2048px width or height.

 or you can just
 {{{
 add_image_size()
 }}}

 Besides, as pointed out by @joyously, it would increase disk space usage
 thus it becomes a ''tradeoff between disk space and user
 experience/bandwidth efficiency''. If, as both my and @joyously experience
 suggest, there are a relative small number of cases where this is
 necessary, such situations can be dealt with the single line of code above
 in a theme or plugin.
