I've started using computers in the 90s, I've seen this every day back then.
Still the question is, does it help? Trying to access an average web app will probably take minutes before the browser may even see an image. If you do everything possible to render reasonably fast on very slow speeds, then progressive is nice. On a fast connection I don't think the average user will notice the difference.
