We need to mention in the autoserialization section that we will automatically ensure that the correct response format is return as per the event we recieved. E.g., even if your handler returns a v1 proxy result, if we detect it is procesing an ALB event we will transform the v1 response into an ALB response. Note that this allows customers to swap integrations with little to no code changes.
