To close the loop on this:

ICANN carefully tracked the likely side-effects of the increase in size 
of the root's DNSKEY RRset to its highest value. We got streams of data 
from most of the root operators for indicators such as query rates for 
DNSKEY, total query rate, TCP query rate, truncation, and ICMP status 
messages, and we saw no indication of significant problems that started 
with the introduction of the new DNSKEY RRset.
