I'm a bit surprised the autoplay attribute - at least how it's been used for <audio> and <video> hasn't been similarly consigned to the dustbin of history.
What is taking so long? /s
(Only a bit of sarcasm there, I actually would like to know...)
`autoplay` is rarely appropriate to use, but not never. If a link named "Play 'Never Gonna Give You Up'" goes to a page with <video autoplay …>, that's fine. If the user is informed that the action they're going to take will lead to audio or video playing, you don't have to make them click an additional thing (a "play" button) to make the content play.
