+Subject: [PATCH] Restore custom InventoryHolder support
+
+Upstream removed the ability to consistently use a custom InventoryHolder,
+However, the implementation does not use an InventoryHolder in any form
+outside of custom inventories.
+
+We can take that knowledge and apply some expected behavior, if we're given
+an inventory holder, we should use it and return a custom inventory with the
+holder, otherwise, create an inventory backed by the intended inventory, as
+per upstream behavior.
+
+This provides a "best of both worlds" scenario: plugins with InventoryHolder's
+will always work as intended in the past, those without will create implementation
+based inventories.
