That's chicken/egg - IPv6 never will be widely used if everyone thinks
that way.
The sense is to break this dependency loop by ecouraging everyone to
use it and not to make it easier to completely disable the support.
As I said: you -always- have an IPv6 connection to the outside world
as long as you have a single official IPv4 address.
Not using it because it doesn't fit in your current network is one
point, but disabling it in a way to make a future step to IPv6
harder is another.
The number of IPv4 only systems is already big enough - we don't need
to build new ones.
