Update to recent discussion: we've now moved several of the
extensions in https://www.mediawiki.org/wiki/Review_queue forward, so
they're actively in design or code review, or close to deployment.
Thanks to everyone, volunteer and WMF, who's been working on this.
Specifically, RandomRootPage by Huji, ShortUrl by then-volunteer Yuvi
Panda, RandomInCategory by Victor Vasiliev, SpecialInterwiki by
Stephanie Amanda Stevens and SPQRobin, SubpageSortKey by Brian Wolff,
OnlineStatusBar by Petr Bena, SignupAPI by Akshay Agarwal, and Score by
GrafZahl are all further along in the review process than they were a
few weeks ago.
