Any patches to wmf/branch_cut_pretest are immediately +2'd so running the test pipeline is unncesssary and wasteful.
I think that can be done by adding a reject-approval to the event. We did something like that on https://gerrit.wikimedia.org/r/c/integration/config/+/793458 which only applies to Code-Review +1 being cast by an approved user. scap-backport is in a similar situation.
OK, this seems to have worked e.g. on https://gerrit.wikimedia.org/r/c/mediawiki/extensions/SiteSettings/+/999891 from LibUp only went into gate-and-submit and never had the test pipeline run, which in general will save quite a lot of CI time. :-)
Nice idea, @taavi.
I'm fairly sure LibUp patches have been configured that way for a while, LibUp will add V+1 to manually trigger test jobs when not +2'ing. But we'll see what happens with the next branch_cut_pretest job when it runs.
