I'm going to be bold and mark this as declined. This is no longer stalled by wl_id, but it seems the current plan (T124752) is to implement something simpler: just adding an expiration column to the existing watchlist table. This seems sensible, especially since it will match how user rights expiration was implemented and thus follow an existing pattern. If anyone disagrees, feel free to reopen this task.
