I mean merely that, when asked "How do I create a new instance from some data?", Swift's preferred answer is "Write an initializer", and thus `init?(bridgedFromObjectiveC: ObjectiveCType)` is a more natural solution than `static func bridged<Policy: BridgePolicy>(from: ObjectiveCType, by: Policy.Type) -> Self?`. Obviously this is a mere style concern and should be ignored if there are good reasons to use the other design, but it seems to me that it deserves at least a little bit of weight.
