At the database level, you should be able to detect RC entries that changed a
particular slot easily enough, by including a join like
JOIN slots ON (rc_this_oldid = slot_revision_id AND slot_role_id = ? AND
slot_origin = slot_revision_id)
If you want to allow for "touched any of multiple slots", that would probably
need an EXISTS. I forget the exact semantics of `slot_origin`, that may or may
not find reverts.
You could also exclude changes that touched any particular slot or slots, like
LEFT JOIN slots ON (rc_this_oldid = slot_revision_id AND slot_role_id IN
(?) AND slot_origin = slot_revision_id)
WHERE slots.slot_revision_id IS NULL
The potential problem with any of these is performance, particularly in
situations where few or no edits pass the filter (cf. T97797
<https://phabricator.wikimedia.org/T97797>). Although we already have such
problems with other RC queries, so one more may not be a huge deal.
