We have three revert tags: mw-rollback, mw-undo and mw-manual-revert. It would be useful if along with the tags we persisted the information on which edits were actually reverted. The information can be later used for analytics or when performing a delayed RevertedTagUpdateJob, see T259103: Run reverted tag update job only after the edit is approved for more information.
This can be achieving by simply serializing the EditResult associated with the revert and storing it in the ct_params field of the change_tag table.
