You can question it, of course.  I question it as well.

However, it is the only solution available today that the operational folks 
consider viable.  The IETF promised something different and has yet to 
deliver, so PI was passed and deployed.  If the IETF does eventually deliver 
something viable, the RIRs will consider deprecating PI.

Keep in mind that, for any solution that requires host changes, "deliver" 
includes being implemented and on by default in Windows.  The IPv6 core 
protocol has only recently achieved this after a decade of waiting, and many 
other pieces still aren't available (firewalls, load balancers, consumer CPE 
boxes, management apps, etc).  Those who propose shim6 or similar solutions 
need to expect it'll take another decade after the ink is dry for their 
solutions to be considered viable -- if ever.  Those running networks have 
to do _something_ in the meantime, however, and the fact that what is 
available offends someone's sense of architectural purity is completely 
irrelevant.  See also: NAT.
