Re: [whatwg/fetch] Fetch body streams are not full duplex (#1254)

Sorry to be that guy, but I just think it would be nice if I could start responding with data from the server while data from the client is still in-flight for easy UI updates is client libraries like htmx.

The lack of proper duplex support is literally the only thing preventing me from doing nice UI updates while a file is uploaded and ingested live on a single connection - and if that connection died before the upload is completed it can easily be detected and tasks can be cancelled and/or rolledback.

I understand this would be one hell of an undertaking for most browsers, but it would be nice if there at least an agreed goal towards this aiming vaugely at some point in the distant future.
