Because the possible sizes on HQ frames are so very large, I tend to think of them as being "regions" in the stream.  Some are have to be received entire before you can do much useful with them (HEADERS, PRIORITY); others can reasonably be streamed (DATA).  HEADERS are the easiest place to deadlock, and one of the holdovers from HTTP/2 is an explicit communication of the largest header payload you're willing to process.
