My understanding is there is currently a correctness issue in regards to NST and SETTINGS, but there is no actual deadlock if a server sends SETTINGS really late or not at all(and doesn't do 0-RTT).  A client can decide to wait until SETTINGS are received before making a request in order to use the QPACK dynamic table, but it comes with the risk that you delay requests for an unknown period of time.  If implementations send requests as soon as possible and make optimal decisions given what they know at the time, then there's no deadlock, correct?
