@jwildeboer well... it is **a** workflow... which has nothing in common to mailing list based contribution.
GitHub/GitLab's PR workflow is an absolute disaster/nightmare for per-commit/patch review. Gerrit does that a bit better with patchsets but it gets difficult to read pretty quickly, even with topics.
GitLab/GitHub is just NOT necessarily compatible with some project's workflow.
I actually wrote a multiple pages long email on why no GH/GL for Yocto a while back, maybe I should put it in an article so it's easier to explain everything instead of being limited to a few 100s of characters at once :)
@0leil Please do! I will also start a blogpost on how Discord etc mess up communication in a project (IMHO) by mixing synchronous and asynchronous communication together in a way that isn't helpful but, again IMHO, damaging to the flow.
