funny, that was not the case with v4 four years ago

    Luca Cittadini, Wolfgang Mühlbauer, Steve Uhlig, Randy Bush, Pierre
    Francois, Olaf Maennel, Evolution of Internet Address Space
    Deaggregation: Myths and Reality, in IEEE Journal on Selected Areas
    in Communications, Vol. 28, No. 8, October 2010.

there seems to be a lot of deagg because of the perception that it
reduces the threat of mis-origination of one's routes.  asia/pac is the
poster child for this but the competition is keen, see geoff's reports.

tl;dr (from the abstract):

    The impact of “bad guys” on routing table size growth and BGP churn
    has not changed for the worse in recent years. Rather, it increases
    at the same pace as the Internet itself.
