This seems to be disabled purposely due to the way that the sorts and such are added on by the API, a sane query can be built (ie no filesort)

It's providing a lot more functionality than DeletedContributions does to begin with

We probably need to create a "mode 4"

CREATE INDEX /*i*/name_title_timestamp ON /*_*/archive (ar_namespace,ar_title,ar_timestamp);
CREATE INDEX /*i*/ar_usertext_timestamp ON /*_*/archive (ar_user_text,ar_timestamp);
CREATE INDEX /*i*/ar_revid ON /*_*/archive (ar_rev_id);

1. List deleted revisions for the given title(s), sorted by timestamp
2. List deleted contributions for the given user, sorted by timestamp (no titles specified)
3. List all deleted revisions in the given namespace, sorted by title and timestamp (no titles specified, druser not set)

List deleted contributions for the given user, in the given namespace, sorted by timestamp

SELECT /* IndexPager::reallyDoQuery (DeletedContribsPager) Reedy */ ar_rev_id,ar_namespace,ar_title,ar_timestamp,ar_comment,ar_minor_edit,ar_user,ar_user_text,ar_deleted FROM mw_archive FORCE INDEX (usertext_timestamp) WHERE ar_user_text = 'Reedy' AND ar_namespace = '0' AND ((ar_deleted & 12) != 12) ORDER BY ar_timestamp DESC LIMIT 51

Starting to do this, then hit a snag. By default NS is set to 0... So we can't just do a NS/User filter, and know whether we want to hit 2 or 4..

So people could then unknowingly be filtering by NS 0, which they may or may not want...
