Diffs to deleted content

Problem: I want to compare deleted content to live revisions under the same title, or live/deleted revisions for a different title. This is especially useful to check whether a page is a substantive copy of the deleted content and is a key tell to determine whether the author is a sockpuppet. I could do this via Special:Diff or the API... but it is very difficult to discover the revision ID. There should also be associated UI improvements to page history, Special:Undelete and Special:Deletedcontributions to integrate this functionality. The ultimate goal is to demonstrate some user conduct partly based on deleted content.
Proposed solution: See above.
Who would benefit: Administrators

Discussion

This one might be too large if it depends on 'unify the deletion systems', as the Phab task does indirectly. --Izno (talk) 23:51, 16 January 2022 (UTC)[reply]
Indeed, it seems this would involve a substantial reworking of how we store and reference deleted revisions that is going to be too much for our team. As such, I'll move this to the Larger suggestions category. Thanks, MusikAnimal (WMF) (talk) 02:01, 25 January 2022 (UTC)[reply]
How non-admins can compare the diff of deleted content when they can't view the deleted page? Thingofme (talk) 14:20, 5 February 2022 (UTC)[reply]
