It's not obvious how or where to submit changes to BitBake, we should have a canonical document that we can point potential contributors at.
Michael: Could you check and see if this is still an issue please?
We have such documents: - https://docs.yoctoproject.org/dev-manual/common-tasks.html#submitting-a-change-to-the-yocto-project (this has explicit instructions for contributing to BitBake) - https://git.openembedded.org/bitbake/tree/README Closing this bug.
