An alternative design, which I would generally consider superior, is to make it easy to undo leaving a meeting. (This wouldn’t work for the host under the current behaviour model, because the host leaving needs to either assign someone else to be host, or close the meeting for everyone. But you could do it this way for everyone else. Whether it would require waiting room approval again would be an interesting question, however. As usual, there are complexities to be considered.)
