Currently, query code still accesses the CatalogCache directly to obtain routing table information for its required namespaces (example). We should get a definitive list of all routing operations that rely on the CatalogCache and tag them for replacement by the RoutingContext. There is a running list here - we should ensure it is complete or fill any gaps as needed.

// Catalog cache access
Grid::get(opCtx)->catalogCache();

// Routing table acquisition
catalogCache->getCollectionRoutingInfo(opCtx, nss);

Query code refers to files assigned to @10gen/query or subteams in the CODEOWNERS file. Helpers directly called by query code that perform direct CatalogCache accesses should also be considered for replacement.
