Since Revision::getRevisionText() uses the old_text field which is obtained by joining rev_text_id or ar_text_id against text.old_id, it can no longer be used with queries based on getQueryInfo() or getSelectFields(), once rev_text_id and ar_text_id go away.
Code that interacts with the text table directly should use SqlBobStore::expandBlob instead. Code that operates on the revision table should use the appropriate methods in RevisionStore and RevisionRecord to access content.
DOD: This task should be considered done when any code calling Revision::getRevisionText() has been, in core and all extensions deployed by Wikimedia, as well as extensions bundled with MediaWiki releases. Other extensions and external tools may be left to be updated later.
