I've created a PR [1] which is intended to do the same for the Confluence Wiki as as the flagged directory entries do for retired websites.
The idea is that there is an ATTIC Wiki, under which the Attic project can create dummy pages. If the dummy page matches the name of a retired Wiki, then an output filter is added, and a banner is added to the page before delivery. For example: Sqoop has retired, so I created the page: https://cwiki.apache.org/confluence/display/ATTIC/SQOOP Once the PR is approved, it should result in a banner being added to pages under https://cwiki.apache.org/confluence/display/SQOOP [N.B. The banner is not added yet, as the PR has not been applied!] If this works OK, then adding the banner will just be a matter of creating a suitable page under the ATTIC Wiki.
