Well, people havn't been at all keen on solutions which would need
fairly significant changes to how the operators do inter-AS routing
(even if they would avoid shifting some aspects of routing to
end-nodes).
Given this high-resistance (rightly, wrongly, doesn't matter) to big
changes in the transit parts of the internet, the only place then to
do it is at the edges: have leaf-sites^Wnodes be more far active in
how their packets are routed (by making deliberate use of the current
provider aligned allocation<->topology transit internet).
What kind of operator are you thinking of btw? End-node shouldn't
bother operators of ISPs really (they'll only get the traffic that
the end-node decided it wanted to send via them, which is exactly
what you have today ;) ). It could bother operators of other kinds of
sites though - but I'm hopeful though that the shim6 mechanisms will
be malleable to site-multihoming, even if initially shim6 only
concerns itself with end-hosts.

Just cause one network is unreliable does not mean that all the
networks the end-node is connected to are unreliable. The end-node
can try figure out which work and which don't and route accordingly.
That's the whole point of shim6 ;).
