Discussed in London; we should mimic whatever H2 does, and there's some uncertainty in the room about what a client-sent GOAWAY is intended to mean.

H2 GOAWAY says:
   Once sent, the sender will ignore frames sent on streams initiated by
   the receiver if the stream has an identifier higher than the included
   last stream identifier.  Receivers of a GOAWAY frame MUST NOT open
   additional streams on the connection, although a new connection can
   be established for new streams.

So HTTP/2 does define it in terms of streams, and a server upon receipt of a GOAWAY frame MUST NOT open more streams, which would include push.  The other side probably can't police you, however, because they can't reliably know that the opening of the stream wasn't already in flight; they'll just ignore it.
