I don't think it should, since the stable branch which is a superset of it should all the patches as well and will fail before backporting to the new branch. Yes, there might be rare occasions where a patch will fail on version branch and not stable branch, I'm not sure its worth the effort of duplicating all CI resources per branch just for it. We already don't cover all flows in CI because there are limited resources, so I don't see a huge difference here.
