<http://http2.github.io/http2-spec/index.html#rfc.section.5.3.1>:

I can’t find anything in the document that clarifies what is meant by the phrase, "it is not possible to make progress on them” (referring to the streams that another stream depends on). What does it mean to not be able to make progress on a stream?

Could a stream dependency be used to ensure that a server queues up another request but doesn’t process it until the first request completes? (Say you wanted to post a message with one API call, and then fetch the new list of messages in a 2nd dependent call)
