how to process packet loss of pipetransport?

Packet lossing may happen on pipetransport that between the routers in different hosts. As I know, pipeconsumer ignore the nack received, what is the consideration of mediasoup do that?

endpoint -> producer1 -> pipeconsumer -> producer2

Will be done when possible.

RTX/NACK and SRTP are being added to PipeTransport. See https://github.com/versatica/mediasoup/issues/352#issuecomment-591723246.
