Embed a slide deck into a post or page

[zu]

It would be useful to have slides as part of a longer article, similar to an embeded slideshare, speakerdeck or YouTube.

It might be possible to tweak the WordPress embed rendering for that custom post type. So you'd paste the presentation URL to embed a slide deck inside a post.

Even better would be a slides/slidedeck block. Similar to how some form, events or slider plugins work (choose slidedeck from within the block)
