Easy - Greater return on the investment; i.e. - instead of getting an IPv4
/4 out of the effort you get an IPv6 Global Unicast Space of 2000::/3 (just
for starters, counting neither the rest of the unicast nor multicast, etc.

Also, the impact of the "changes required" is close to the same in that
every node needs to be touched - that is the hard part, getting updates
deployed.  *(Unless you want 240/4 to be a special/limited use case - in
which case the effort is smaller, but so is the reward ...)*
