Some container images are not built on dev (#750)

While working on #729, I realized we have filtered out some image builds targeting dev now that the feature branch is gone. This change will allow more pre-release evaluation of constraints as they are developed.

I should have PRed this or delegated it after we merged in the long-standing feature/external-constraints branch, but this miss was an oversight on my part.
