Hmm. I didn’t consider it like this, but the new Transbay Transit Center has trash cans of a similar design all around the rooftop park. They are enclosed, but the enclosure is completely transparent so you can easily see in the bags. Honestly there’s a number of good reasons you might want that design though, e.g. needles have been an issue around San Francisco.
