Well, if the DNS root servers ceased IPv4 service it'd be pretty much

Given the reality of fragmenting the DNS -- including its root -- that's an 
action that well might backfire.  Current fragmentation is constrained; this 
could plausibly motivate more people to pursue other paths and thereby blow 
things up.


I wouldn't suggest doing it without A LOT of coordination with
stakeholders.

While we're on the subject, someone else suggested that one source of
authority would be the Tier-1 vendors, the other would be governments.

Tying the two sub-threads together I believe there's sufficient
authority vested in the DNS management and RIRs to accomplish a
transition to an, effectively, all-IPv6 internet without either of the
above leading tho they would have to follow of course.
