 ### Sending ACK Frames {#sending-acknowledgements}
 
-An ACK frame SHOULD be generated for at least every second ack-eliciting packet.
-This recommendation is in keeping with standard practice for TCP {{?RFC5681}}.
-
 An endpoint MUST NOT excessively delay acknowledgements of ack-eliciting

If you send an ACK for every other received packet and drop all older acknowledgments, then you use at most 19 bytes for an ACK, probably less.  I don't think that will break any limits.
