Hello,
I have wgCodeReviewDeferredPaths on mediawiki.org which let us automatically defers revisions based on a path.
The initial list is currently:
+$wgCodeReviewDeferredPaths['mediawiki'] = array( + '%^/trunk/extensions/SemanticForms%', + '%^/trunk/WikiWord%', +);
The bug report was: https://bugzilla.wikimedia.org/23494
