Your wild guess is wrong, there are no queries possible that exceeds > 512 udp size. A QNAME has a maximum length of 255. The wording used "reasonable queries" originates in Ronald van der Pol's paper on 'Adding IPv6 glue to the root zone'. My wild guess is that Ronald might shed some light on this. Gut feeling is that reasonable in the context of Ronalds paper means queries that conform to all DNS specification.
