We can do this, but what does it really get us? On the sink side, we
know what restrictions we want to place on the input, and it's
reasonable to assume anything unspecified is fine (if it's not, it
should be specified as a restriction anyway).
On the stream side, we're not providing the information as a restriction
- we're saying "I have this stream, it can be with one of these
formats/properties, find me a sink to plug into". What would an optional
parameter achieve here?
