Why are Netjack2 master ports marked Terminal?

[mildsunrise]

Netjack2 creates from_slave ports and to_slave ports. Why are these ports marked as terminal? They are not edges of the graph; data coming at to_slave ports is processed at the slave and sent to from_slave afterwards.

It also makes sense if you think that the slave's client contains a sub-graph; data is processed by the sub-graph and returns to the master graph.

Sure, they are special ports because the data is not processed locally but sent over the network. Sure, data coming at from_slave is not necessarily related to to_slave. Still, a Netjack2 slave is intended (the docs insist on that) to do only processing and not interact with other soundcards or hardware.
