I am for it as long as I am still able to use ``as`` to go from an AnyObject to an NSObject Subclass. 

func executeFetchRequest(request: NSFetchRequest <x-quickhelp-usr:c:objc(cs)NSFetchRequest>) throws -> [AnyObject <x-quickhelp-usr:s:Ps9AnyObject>]….
class MyRecipeMO: NSManagedObject {….

….
 let existing = try context.executeFetchRequest(fetch) as? [MyRecipeMO]
….

If am not able to do the above then this change would make it much harder to work with Core Data and JSON API

seems like casting in java
