I'm sorry, but the "people need to whine more" solution does not
scale. (What makes you think I have not reported these issues?)

What is your point? No one is claiming a majority. The point is we
should strive to not break ANYTHING. That is how transitions are
encouraged: when you can honestly tell people that if they turn on
IPv6 they will break *nothing*. That *no* clients will suffer. That
*no one* will complain. Not that "only a minority" will have
problems.

Given the limited data you provide, it would appear that you would be
better off using IPv4 for communicating with this particular host.
You might say that someone who is not emotional about the situation,
and cares only about network performance, would in this case "prefer"
IPv4 over IPv6. Correct?
