Returning a collection - transferHandlers to be called

[tbrannam]

Given an exposed interface.

interface Service {
 find: (x) => ClassInstance
 findAll: (x)=> ClassInstance[]
}

I can properly call both methods - but the transferHandlers implementing ClassInstance does not get called when handling the response from findAll method - resulting in issues on the other side.

Are nested - non-transferable objects expected to be serialized by default? Implementation says no since only the root return value is passed to toWireValue .

Is it expected that the custom transferHandlers should inspect canHandle values for expected collections and serialize them directly?
