That's a cool idea, and we'd be interested in accepting such a feature PR.

I think we should take this one step further: the markdown rendering should allow for using plugins explicitly installed and allowed by the user (with a customary XSS possibility warning).

this might be possible with the OUI markdown renderer by adding https://github.com/temando/remark-mermaid as a plugin
