      This is a follow up to SERVER-86237. We decided to delay this piece of work because it requires deciding how we want to handle queries which could generate covered plans.

      The current express path is set up to always fetch the whole document, but that may be particularly undesirable in the case where we have a single field index, and inclusion projection on just that field, and the matching document is huge.
