The additional implementation cost is negligible compared to the whole
priority stuff, isn't it?
Also we did similar thing in WINDOW_UPDATE frame; checking stream ID for 0
and non-0 case.
My proposal is also not affected by the pathological case where the stream
in the header disappear due to the asynchronous nature of the protocol, if
endpoint just wants to change the weight of the group.
