Dynamic Open Graph images for topics?

I've seen a few disparate topics related to this subject, but I'd be curious to know if there has been any consideration for generating dynamic Open Graph images for topics similar to Reddit.

When links to my community are shared, I'm thinking about the best visual to represent all links and it can be hard. Should it be a CTA to join? Preview of what's inside? Something generic that just shows the name of my community? I think all are good answers....depending on the link being shared.

Solving at least for question #2, it would be great if Discourse would dynamically generate the Open Graph image for the topic that was a preview of the topic (e.g. title, category, tags, maybe user profile picture, etc.)

Discuss this on our forum.
