      Right now there's no way to tell what underlying query will be used for an aggregation pipeline; knowing that would help with performance issues. As well as that, as we apply more optimizations to pipeline execution, we'll want to be able to see the original pipeline specification as well as what it has been transformed to by the optimizer.
