[ppml] [address-policy-wg] Those pesky ULAs again

I will agree with this..  though I might have phrased it differently.  

Rather than mandate how organizations must use portions of their
allocations, why not just let the whole thing be publicly routable?
Then if an organization decides to use part of their allocation for
private routing they can choose a block and quantity appropriate for
their needs.  

Just as today we block private addresses at the network edge, we can
continue to do so for IPv6.  IPv6 is bigger, but it's not magic..  

I have access lists in place on my routers to prevent private IP routing
and IP spoofing..  I assume (yeah, I know) that most responsible
sysadmin's do the same.  

I really don't understand the controversy over or need for ULA-C.  Feel
free to honestly educate me.  I like feeling educated.
