If we do not have a global source address, sending packets via a router
is pretty much guaranteed to violate a number of RFCs.  

So hoping that a router will tell us by means of ICMPv6 what we already 
know (and hoping that it is even able to do so, which implies special 
handling over there to get the ICMPv6 to a LLA out the correct interface) 
does not sound like a good plan forward.
