      The initial implementation in SERVER-129261 assumed that no single table access paths (CanonicalQuery in any join graph node) had a projection. However this is not true as our existing rewrites may produce a projection on the base node. SERVER-128364 will allow other nodes to have projections as well.

      This ticket tracks work to encode projections into the cache key.
