With this reasoning, the best would be to totally to drop IPv6 support
from Debian.

In the past we have to often disabled unified IPv4/IPv6 lookups after a
few complains. This way we never progress. The solution is to keep that
enable and try to workaround all the broken servers. But people should
accept it will take time, because the number of case it's only limited
by the imagination of engineers... We already added a few workaround
that improve the situation for a lot of persons. But there are still
workarounds to add.

That said if before the release of Lenny we are still at this level of
incompatibilities, we should keep back to the previous behavior from
Lenny... and make a lot of people unhappy. Unified IPv4/IPv6 lookups
create some problems, but solve some others. It's a compromise.

We accept everything from the servers, it's just that they do not apply
this principle and either don't answer or send wrong answers. We can't
create missing information. They are conservative in what they accept,
and really liberal in what they produce.
