As explained by Dan, that will not help for the merge request builds, because those are executed in the context of the submitter's fork and as such don't have access to any runners we might deploy ourselves. It would help speed up the post merge phase, but once we move to a merge request workflow we'll want to test as much as possible at the time the merge request is submitted, and there won't be much that needs to happen after the changes hit master... So dedicated runners might actually not be useful outside of supporting non-Linux targets. -- Andrea Bolognani / Red Hat / Virtualization
