I'm an embedded system designer, and the system I develop works fine under
IPv6. We say we don't support it, because we don't specifically test it,
but a lot of the time the applications are1 actually running over IPv6
without anybody noticing. The Windows GUI pieces can't configure IPv6
addresses, but we really prefer running with link-local anyway.
