 Description   

After discussion we decided not to do this as part of SERVER-45620 because it isn't clear which values should supersede others.

Correct, we are not planning on doing that in SERVER-45620

ted.tuckman I don't think we plan to do this if it doesn't happen in SERVER-45620, is that your understanding too? If so I think we should mark this as related to the epic to track alongside the other future optimizations.
