      A common agg query is a $lookup followed by an $unwind. When implementing $lookup pushdown into sbe we decided to not support absorption of $unwind into $lookup and execute in sbe to keep the scope smallish.

      The owner of this ticket should investigate and implement $unwind pushdown in $lookup when executing with sbe.
