> Sloppy apps ignore this, but the devs are quickly notified.
Anything that increases friction for developers is bad. The API for HiDPI should be so seamless that the only thing developer does is to provide higher resolution bitmap icons.
Imagine what web app developers need to do when their users switch from a regular display to a HiDPI display. They do nothing; the browser knows how to scale on its down. And that should be the bar we are aiming for.
