@Maegereg This PR looks good generally and should work well. Do you need to make similar changes to the merge_queue.yml file too?

Some jobs, like package, are shared across these files. Is it possible for us to the job once and then import it into the other yml files?

I wasn't planning to - there's nothing in the merge queue that's repository-specific. It won't cause any failures in a fork.

Looks like that should work. I can work on that in a follow-up issue. I filed #46
