why is ipv6 fixly compiled in latest F15 and all F16 kernels?

Yes, I have it (as You wrote, on kernel cmdline - as having it in
sysctl.conf seems not enough). But this nothing change on fact that
1) I have unwanted things included in kernel, and
2) something (NetworkManager or other malware;) can easily activate
it.
As module, I can better control how use it and save memory too
(although when ipv6 stack is disabled entirely, memory requirements
may be lower - I not study about this).
