Currently the operator requires a SortKeyPattern to generate a SortKeyGenerator to generate values to compare. If the inputs given to the accumulator were already sort keys, which should be available via {$meta: "sortKey"}, then it should be faster. This will not only boost some performance, and make it easier to build syntactic sugar for a $rankFusion stage, since we won't have to generate and pass along a sort pattern.
