> With this text, should't PATH_RESPONSE be non-ack-eliciting?

I think there is no need for such change, because a frame that's ack-eliciting does not necessary mean that it needs to be retransmitted. 

Quoting section 13.2 of the transport draft, _QUIC packets that are determined to be lost are not retransmitted whole. The same applies to the frames that are contained within lost packets. Instead, the information that might be carried in frames is sent again in new frames as needed._
