I actually like this better than #3141. It is simpler.

@kazuho and I discussed the point that this solution might cause endpoints to lose some RTT and congestion signals since not all ACKs need to be received, and we believe that is ok. It might be useful to recommend that endpoints bundle ACKs when sending initial and handshake packets to allow the peer to get RTT signals as early and frequently as possible at the start of the connection, but that can be done separately.
