The extension we are developing allows complete bidirectionality to HTTP, so a server can initiate a request/response to the client.  The H2 mapping of this extension uses a client-sent GOAWAY to clue the server in to stop doing this.  I don't know that missing this will break-badly; it probably depends on what application developers do with the bidirectionality.  It's asymmetric with H2, seemingly because we think we got it wrong in H2 and are trying to correct it?  I'm trying to say there is some value in keeping it symmetric.

I think Lucas correctly identified the semantics of what GOAWAY is - STOP_CREATING and PROCESSED.

As mentioned in the original issue, anyone writing an extension can also extend the GOAWAY frame under that extension that does what I proposed, so doing nothing is of course viable.
