If you already have a chat infrastructure set up with all the bells and whistles, then you probably don't need this; it is a different kind of workflow.

But one workflow for it would be open source projects that prefer not to have to maintain additional infrastructure and just want to inline ephemeral communication w/o having to keep it forever; then they make a design decision and have everything that is finalised moved over and documented in the wiki.
