There are a couple of places where macOS still has Aqua-style icons. Not sure I should name them in case someone sees this and removes them, but... eh... set up a VPN but leave the credentials blank so you're prompted when you connect: that dialog has a beautiful icon.

It looks _just fine_ on a Retina display.

When Retina displays were introduced with the iPhone 4, gel-style iOS also looked just fine.

In print, we're interacting with paper and a fake reflective style looks odd. On a computer, we're interacting with glass and something reflective or high-detail feels very suitable. It matches the look to the medium.
