I disagree.  From my own experience the issues brought up in the above are 
simply not important for the majority of network applications which don't 
really care whether a connection is made by IPv4 or IPv6 nor for the 
majority of users who shouldn't have to know anything about the underlying 
network.

I think Section 3.7 of the API has actually made it relatively easy for 
most developers to add IPv6 capability to various apps that were 
previously IPv4-only.  If the recommendations in the above had been 
followed I think you'd actually see a slowdown in updates to various apps 
since developers would be forced to write/debug significantly more complex 
code.
