Disclosing future plans, prototypes and possible features of a large company is often a difficult subject matter. I’m sure they are trying out different things and building different features, but talking about them can be problematic for many reasons.
I’m pretty sure they’re disclosing as much as they are able to.
Beyond that I don’t see how hard it could be to speculate over what actual functionality they are intending for this system, and as such see how the IRC protocol was not built for that kind of features.
