The [ACK frame section](https://tools.ietf.org/html/draft-ietf-quic-transport-24#section-19.3) of the Transport Draft should explain what to do when generated ACK is too large to fit in a packet:
1. Generate a shorter ACK frame (instead of aborting connection or erroring out).
2. To generate the shorter frame, don't include older (smaller) packet numbers.  (As opposed to not including newer packet numbers.)
