Via the
Query::HINT_INCLUDE_META_COLUMNS
hint you can now always get access to meta columns regardless of type of hydrator. The query hint is not used in the code base right now.This is a different approach than what #6396 proposes, but that is necessary to get this backwards compatible. By automatically passing this now for ObjectHydrator sub classes we could break existing code.
Fixes #6396
