Chunk type extensibility is under-specified #9

Closed martinthomson closed 3 years ago

martinthomson commented 3 years ago

I'm assuming that the model here is "MUST-ignore unknown", but it doesn't really say that. It probably needs a little more language about how a design might be able to decide that a peer supports a feature, such that it can continue to use the extension without fear of wasting bandwidth.

We already have this text in the Stream Chunks section:

Endpoints that receive a chunk with an unknown CONNECT-IP Stream Chunk Type MUST silently skip over that chunk.

But I agree that we can flesh out our Extensibility Considerations section.
