In the
reactive-streams initiative the github repo has worked pretty well in order to pull together people from different organisations to work on a shared idea.
So there is at least once precedent where this seemed to work fine. I believe it started as a mailing list prior to moving to github, but can not comment on how well it worked.
Had a short internal debate if a mailing list like `akka-discuss` wouldn't be better - but I guess having it as issues makes it easier to see when a conclusion has been reached (ticket closed), and @ping people as well.
Sounds to me like it may be worth a try.
