Making DNS resolution configurable (for example by allowing the user to
supply their own resolution function) in the stdlib's network APIs
doesn't sound like a really bad idea to me. Of course, a "no_ipv6" flag
would scale poorly and would therefore be a bad API.

I don't think moralist arguments should have a weight when deciding
which features we add. If developers want to introduce bugs or
limitations in their software they will always be able to do it.
