@antonakospanos after checking how we have done this in the past (e.g. with giso https://github.com/Workable/cli-tools/blob/56c84a8e350f735fc7f82cafc75f88280272166d/giso/helpers.js#L31) force as default seems reasonable.
But again ability to learn that remote has changed and ability to force manually would be nice to have.
