Album artwork feature for .wav files inexplicably removed from iTunes.

Hello, I was wondering if Apple would please allow us to display artwork in iTunes for albums that contain .wav files. Waves just sound better to me. I remember back in 2004 or so this feature was available in iTunes, nearly a decade ago, but now it has been inexplicably removed. I am not interested in compromising the sound quality of the .wav file by converting them to compressed formats, Apple lossless, or even Apple's rival to the .wav file. Thank you.
