      Our current input validation for $scoreFusion enforces that none of the input pipelines can modify the documents or their fields in any way (eg. $project, $group etc.). Because $scoreFusion gets desugared to a pipeline with stages like $group and $project that aren’t legal, nesting $scoreFusion doesn't work.

      The same idea also applies to testing $rankFusion in $scoreFusion.
