## Which issue does this PR close? - Part of https://github.com/apache/datafusion/issues/20173 ## Rationale for this change I am debugging an issue related to the interplay of pre-existing orderings, filtering and projections in FileScanConfig. As part of that I am trying to understand how `Statistics` were handled by `FileScanConfig` -- specifically when relatively speaking are the projection and filtering applied I believe the statistics are (supposed?) to be *before* applying the Filter and Projection from the scan, so let's document that better. I also would like to use this PR to validate my understanding of the intended design ## What changes are included in this PR?
