I think the image trick is more attractive than <a ping> because it's easier for web developers to use. But I'm not convinced it's the cleanest method we can come up with. If we are expecting web developers to change, then I'd prefer something more explicit link asyncPing(url). The benefit is that it doesn't tie up connection limits like image loading would, and hence shouldn't impact the navigated page's loading. The UA is then free to pick the best time to do the ping, i.e. when network activity has died down.
With the Image trick, web developers don't have to change, other than to get rid of the busy loop. I wouldn't be too averse to also adding an explicit ping API, but it seems to me it's possible to do many of the optimizations you describe for the Image-in-unload trick.
