Could be hard to convince the developers to do so, and in my opinion 
distribution-specific patches should be used only when necessary, not as a 
normal way to proceed.

Unfortunately i don't have access to the POSIX specification, but the 
opengroup says that by default bindv6only is 0.

http://www.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html#tag_15_10_20_02

So basically the developers will assume this value and will probably reject 
bugreports claiming that the assumption is wrong.
