The closest we have in existing RSSAC 002 stats is the table that gives
the query packet size distribution (see e.g.
<http://rssac-stats.isc.org/rssac002/2017/03/traffic-sizes/f-root-20170326-traffic-sizes.yaml>)

However these are binned in multiples of 16 octets, and also do not
allow you to differentiate the queries that arrive with the 11+ octets
that an EDNS OPT RR contains.
