PM-2218 was completed for server v7.0. This epic was one of the blockers listed for adding read concern majority support for listDatabases, listCollections, and listIndexes in REP-106. Is it possible to add that support to these commands now that the epic has been completed?

Mongosync has two separate code paths for pre-v6.0 and v6.0+ server versions that use listCollections and $listCatalog, respectively. If the above commands supported majority read concern we would be able to consolidate this code and rely the publicly documented commands rather than $listCatalog.

Editing this since it might be a non-trivial ask to backport the changes to 6.0 (but worth discussing if possible).
