Thread:Talk:About/Creating New Redirects/Historical yet linked

Needs a Redirect (Archive) links to this page, yet it is marked historical as an archive of the corresponding page in the TV Tropes snapshot. So All the Tropes needs its own "how and when" page. If we're relying on WMF's help pages for the "how", we need at least a "when" page to explain the rationale behind deletion of "unused" redirects.
