* A new API is provided to support non-production testing infrastructures, allowing a client to cull all orphaned UIDs via ``DELETE`` on ``<api>/reserved/uids/orphans``. Note that *no guarantees* of API stability will ever be made for resources under ``reserved``. (LP: #1420083)
Also:
- Allow @dbconnection methods to be @staticmethods taking only one argument, the store to perform the query on.
