And then <attention/> but not actually <attention/> should be it's own
element that can but doesn’t have to be generated by the MUC service.
Also, random thought - it'd be great if I could draw someone's attention to a particular message without having to simply send a message of my own mentioning them.
I'd say a solid 10% of mentions in Slack, possibly more like 25%, are people just mentioning people in a thread. It'd be nice to have a protocol-level way of doing this, like a reactionish mention.
