 An HTTP request/response exchange fully consumes a bidirectional QUIC stream.

After reading the whole section, I think that while the section intends to talk about both push and requests, this paragraph is specific to requests.  I've added more discussion of push streams above, but I think I'm going to leave this particular paragraph alone, modulo fixing @LPardue's initial suggestion.

+Pseudo-header fields are not HTTP header fields.  Endpoints MUST NOT generate
+pseudo-header fields other than those defined in this document, except as
+negotiated via an extension; see {{extensions}}.
+
+Pseudo-header fields are only valid in the context in which they are defined.
+Pseudo-header fields defined for requests MUST NOT appear in responses;
+pseudo-header fields defined for responses MUST NOT appear in requests.
+Pseudo-header fields MUST NOT appear in trailers.  Endpoints MUST treat a
+request or response that contains undefined or invalid pseudo-header fields as
+malformed ({{malformed}}).

Nope, it actually does wrap this way by sheer coincidence.  (Or @martinthomson was playing a really long prank in RFC 7540.)
