(Forked from bug 21279 comment 33 per Brion) Per bug 21279, code will be patched so that deleted revisions can be referenced by their rev_id (to ensure that links using rev_id will work regardless of subsequent delete/undelete activity). Once this is done, can special pages such as [[Special:Undelete]] and [[Special:DeletedContributions]] be modified so that the links they show to deleted revisions and deleted revision diffs use rev_id rather than page/timestamp. This would ensure that any links posted on-wiki or noted by users for future would be guaranteed to always work (or at least be easy to trace) regardless of future deletion/undeletion, unlike page/timestamp based links which can fail.
