Indeed, the first request in H1 is special in that it is not automatically retryable. In H2 it's different, all requests are totally independant and there is not even any real ordering. Since it is possible to use GOAWAY to cleanly close a connection, no H2 request suffers from the limitations of the first H1 request, so none of them is marked first. At the very least this should be mentioned in the doc. Do you have a particular use case that relies on this and which would need any form of emulation of this older behaviour ? I couldn't find any but maybe there are. Thanks, Willy
