Before:

* SQL-backed queues are created implicitly - by inserting items in `civicrm_queue_item`
* Non-SQL queues are not visible/discoverable

After:

* Any kind of queue (SQL or non-SQL) can be registered and discovered via `civicrm_queue`

Comments:

* This will make it possible for the standard/generic/default background-worker
  to discover what queues it should monitor.
