The END_SEGMENT flag is defined for HEADERS frames, but it seems to be meaningless. A literal reading of the draft seems to say that such a frame cannot be coalesced with subsequent CONTINUATION frames, but those frames do not also have the same (useless) segmentation capability.

Why not let END_SEGMENT and END_HEADERS be the same bit? Then headers be treated as the first segment of any stream, by some simplistic intermediaries. It also reclaims a flag bit, as they are running into short supply.

Also, is END_SEGMENT required when END_STREAM is set? It seems it should be, for the sake of protocol regularity.
