      SERVER-81466improves how projections are generated by Stage Builder. It was merged Nov 4th. Stage Builder for window function can use this change to optimize the partition expressions for $linearFill to avoid redundant $project/addFields.

      The limitation placed in https://jira.mongodb.org/browse/SERVER-83490 should be removed as part of this work.
