I'm rethinking thi, because this breaks the implicit contract in gr.ChatInterface, where a user sends a single message to the chatbot and gets a single response. This would be problematic if you were to use the gr.ChatInterface in an API setting as the return type would no longer be a single message. Since this is a use case we are looking to grow and I'm not sure if there's a strong reason for this particular feature^, I'll go ahead and close this pR
