If the versions are locked, then after the first download, nothing should be downloaded again unless I explicitly change a requirement and/or a version. So after the first time with a given set of requirements and versions, I suppose "go run" would be fine since it won't actually download anything.
But for that first time, I still want to separate the two steps, for the reasons I've given elsewhere in this discussion.
