Embed an Express document on a web page

18 months on from the first post here where someone was complaining about Embedding being taken away after Spark... Are there really no plans to allow embedding of Express content except Web pages?
Not even Presentations? 

It is a big missing feature compared to Canva, Powerpoint, Google Slides and all the other presentation tools. And all content platforms, for that matter. It seems weird.

Perhaps management might be worrying about the cost of data usage and editorial issues. That doesn't make any sense though, because you already provide Share links to view a document.
But it could also be an upgrade motivator for Premium users, CC, Enterprise & Campuses. Although it's pretty fundamental.

Somewhere else here an Adobe Campus professor was saying they were abandoning Express for presentations and going back to powerpoint because of issues with forced logins when embedding Express presentations on their Learning Management System. They seem to have embedding enabled for Presentations? It isn't even available for me for presentations as a Premium user.

The only thing it's available for is a published web page - which is the last thing you need to embed, because you'd need another web page to embed it on!

That doesn't make any sense either, so it doesn't feel like this has been thought through. Or that anyone realises it's a core missing feature.

It just needs a simple iframe code with a url on the Share tab. For presentations at a minimum - but preferably for videos and images - without huge borders or login screens.
