I'm aware that routing table bloat is a problem, I'm also aware that just
doing what we do today tomorrow will probably cause lots of expense,
failure, or pain at some point in the future. I can't see that source/dest
pairs being basically meaningless and large sinks or sources of traffic
being anonymous is going to help either. (shim6 provides the possibility
for end nodes to 'renumber' and change their source/dest at will,
potentially playing havoc with traffic patterns, potentially even inducing
'failure' in the network interconnects along the way.

agreed.
