You&#x27;re not &quot;combining&quot; standards though. As other comments pointed out, this is not a subset of html. It&#x27;s a separate spec, based on a subset of html, which is different enough that it&#x27;s not quite compatible. For example, what&#x27;s with the amp-prefixed tags? Why amp-img instead of img with data-amp- attributes?<p>You also didn&#x27;t address my first point: If you&#x27;re building this for people who don&#x27;t make the effort <i>right now</i>, why would they suddenly make a seemingly bigger effort to support something they haven&#x27;t even heard of before today?
