draft-ietf-v6ops-addr-select-ps-02

I'm reading draft-ietf-v6ops-addr-select-ps-02 and I found something  
that I find somewhat troublesome:

2.2.1. IPv4 or IPv6 prioritization The default policy table gives IPv6  
addresses higher precedence than IPv4 addresses. There seem to be many  
cases, however, where network administrators want to control the  
address selection policy of end- hosts the other way around.

I have a hard time believing this is true. Why would anyone want to  
enable IPv6 and then leave it unused? And if it is true, it's highly  
problematic: if IPv6 capability is available but not used, this means  
that problems (that are common when deploying new technologies) will  
remain unseen and therefore unfixed.
