Well, that part of my e-mail was a bit of frustration speaking - I've
been advocating IPv6 for over 20 years now, and while large parts of
the access networks are offering IPv6 now, other parts are still being
*built* with IPv4 only, or stubbornly stick to IPv4 only...  thus, double
work everywhere, not only in OpenVPN, seemingly for a lifetime.

As far as OpenVPN is concerned, I am not aware of any plans to remove=20
IPv4 support.

The extra code adds some maintenance and testing effort, but since this
is all in place now (especially the test setups with "connect over IPv4
or IPv6" and "send IPv4 and IPv6 packets through the test VPN") it would
be more work to rip out IPv4 now... :-)
