If one wants to see the merits or at least the experiences of a major language from a commercial entity going open source on GitHub, where all discussions, language features, issues, and code itself is in that one place, take a look at Apple's Swift.

Edit: Looks like Swift doesn't use GH for issues any more.

Swift switched all their issue tracking to Jira a while back

Swift doesn't seem to be using GitHub's issue tracker, wikis or anything except the code hosting really.

Well they use code files for discussions, so it's a bit different.
