But nothing prevents you from running on a kernel that does not have
IPv6. The requirements are only about IPv6 support in the toolchain.

Maintaining support for non-IPv6 toolchains was becoming quite a
problem, as more and more packages were breaking with such toolchains.

And come on, we're in 2016, there is no more IPv4 available, it's time
to switch over to IPV6! ;-]
