For me, the sentiment derives from the discomfort of knowingly  
deploying something that is (arguably) broken.  I suspect if you went  
back in time and asked Vint or Bob Kahn or any of the other original  
net geeks if they thought IPv4 would ever really be at risk of  
running out, they'd laugh at you.

Hmm.  I would've thought this would be pretty close to the actual  
definition of "stewardship".

No, market and operational realities change IETF designs as they also  
change RIR policies.

Well, you might on your phone if it is the gateway for your personal  
area network, connecting all the biosensors and other gadgets  
attached to you.  You probably wouldn't run a _server_ on end devices  
like your TV, however I suspect you might on your residential gateway

While I might argue the IETF long ago gave up on running code, I  
think the issue here is one of perception.  Some might argue that due  
to the fact there is very little actual operational experience with  
IPv6 and, in particular, essentially no operational experience with  
scaling IPv6 anywhere near what it is expected to be able to do, that  
the "working code" of address allocation for IPv6 has not yet been  
defined.  What I might suggest we have is an evolving working group  
draft that we're just now getting to actually implementing (and have  
already found some warts)...
