Another point against a periodic job is that it would be a change from what we're doing now, where constraints are updated as soon as the git cache is updated. I think we should publish using a post-merge job. The job isn't expensive, right? It's just copying some files out of git onto the web server? Do we really land 20-30 changes to the constraints list on an average day?
