Hello. How about little expansion of this option? At this moment I can close namespaces with $wgNamespaceRobotPolicies and robots.txt, but it can not prevent indexing and following links by search spiders.
Do you have any evidence that search engines index pages with <meta name="robots" content="noindex,nofollow"/>?
No.
Then there's no point in this change.
