People opt to not have IPv6 support in the kernel because they don't need it,
they don't want accidentally get out through IPv6 just because someone
sent out router advertisements in untrusted nets, or because some routers
do not cope with AAAA questions and don't answer, causing timeouts.
There are always possibilities where people would want that (me not included),
or where people would need that.

Sure. But there are recommended ways on how to program with sockets to
support both IPv4 and IPv6 and it looks that yours is not one of them.
Might be a sign of bad quality if it does not depend on the availability
of IPv6 itself.

How grateful. I'll take my share of that too.
