And while we work out IPv6 and improve it, all users should be 
vulnerable to current IPv6 problems? Are they supposed to be guinea pigs 
for ipv6 development?

Fedora users in particular, including developers who are not concerned 
with network apps, and junior sysadmins who have Fedora as a learning 
tool, should be exposed to current IPv6 vulnerabilities?

The same way Fedora users get SELinux active by default, and iptables 
firewall rules, all in the name of security, they should *not* have IPv6 
enabled by default. Those who wish to learn about and contribute to 
improve IPv6 could enable the feature themselves, not the other way, as 
it is the default for Fedora today.

See you yourself took care of disabling IPv6, but how many computer 
users will know they should? And how many Fedora user will know? 
Installation defaults should serve the majorty needs, not the IPv6 
development agenda.
