I've actually changed my mind on this, if you're working in a project that's doesn't have a ton of early-lifecycle v0 packages. If there is a lot of quick churn in your dependencies, yeah you want to devote dedicated engineering resources to keeping these up-to-date and regression testing things.

If everything is pretty stable, it's nice to have each developer share the work with keeping things up-to-date and functional. Broad automated test coverage makes this a lot easier of course.
