Hi David,

I was sending this request to exactly understand if or what the issues are/could be in not having the DATA frame. Can you maybe further explain which issue you see?
I can't speak for David but the issues I forsee come from additional code paths needed to support the feature. The frame parsing code needs to become HTTP method-aware, which is not the case in the implementation I own.

Not sure I understand this correctly. Without the DATA framing you would not need any frame parsing anymore, you only have to remember that a certain stream is converted into a forwarding stream and blinding forward all payload from that stream. The whole point is that then no additional HTTP logic would be need anymore.

With QUIC chair hat on: this is very late to be proposing design changes. It might even be too late. I'm setting a high bar here for compelling evidence or support that something needs to be changed.

I know… that’s why I’m trying to understand the implications instead of just raising an issue on github.

Mirja

Lucas
