Maybe it's better to have views in the first place, and to require (though it can only be enforced at an administrative level) external services to query against those views. We won't have to do this switch to a view, we've paid that upfront. We can then include a version number in the view name, similar to how we do with APIs. So if we introduce changes we can keep services which didn't need that change outside the blast radius. And we have a limited ability to enforce contracts and declare some columns internal.
