If it is reasonably cheap to have, things like that are a nice bonus
also helping communication in text-only channels.

Of course, "reasonably cheap" is not necessarily easy to achieve.  So
unless there is a more concrete application/demand, I would not even
accept this as a wishlist item since it might keep contributors from
working on more important things.

If somebody still decides to contribute such support in a reasonably
finished way...
