Yes although it's a bit off topic I think the ideal workflow would be to have one forum only and make the GitHub issues readonly. Then there would be some easy way for moderators to transfer bug reports from here to GitHub.
I'm saying this because somehow the high quality bug reports are often on the forum, while people post random stuff on the GitHub bug tracker (probably 90% is non-actionable). So with readonly issues and easily transferable Discourse bug reports we'd have the best of both worlds.
