Thread:Talk:Requests for comment/New sites system/Bug 24748 – Create generic Wikimedia interwiki/reply (4)

Not local to the wiki. Local to a central wiki. The request basically wanted an interwiki with interwiki links inside that. If you add forwarding interwikis to a central place like Meta (something easier with a nice ui that makes people not care about it not being dynamic) then you can get the same result by using Meta as that central interwiki.
