For HTTP/2 unary, should we fix it?

Maybe we don't need to fix it, refer to this link: https://stackoverflow.com/questions/77520309/why-is-content-length-header-not-sent-over-http-3.
@oxsean What do you think?

[oxsean]

@AlbumenJ @finefuture I think END_STREAM flag is enough, because END_STREAM flag is mandatory.
