Regarding the proposed permissions, I would like stricter permissions. I think a committer should be able to stop-start-cancel jobs. But I think only admins should be able to create new jobs, otherwise we run the risk of the CI becoming a mess of jobs that nobody owns and maintains. Please let's only have the jobs that are needed, supported, maintained and have an owner on CI and agreed on the mailing list.
