Yes.   Basically, the tun interface is now always in "dual-stack mode"
on those platforms where it matters (some, like NetBSD, can have=20
"IPv4 only mode" or "dual stack mode", and the latter was "newly added"
some 10 years ago...).

IPv4 is not going to be broken :-)

The only user visible change *expected* by this change is that previously,
"ifconfig-ipv6" would be rejected unless "tun-ipv6" was also configured,=20
and now this dependency is gone - if you configure (or push) ifconfig-ipv6,
you get dual-stack v4+v6, if not, you get a dual-stacked tun interface
with only IPv4 active.
