Are you saying that you believe it is scalable for every

sets to use?
No, I said it's scaleable for enterprise /sites/.
I'm presuming shim6 is to allow a 'split' mode of operation, where
end-systems on a 'shimmed' network don't know of shimming, but the
shimming is instead on a subset of hosts (at the edges).
I don't know whether that presumption is valid.
Further, are you saying that you believe it is scalable
for every end-system in the Internet to *require* such
information to support site multi-homing?
I didn't and would not say that.
And BTW, if so,
how do I communicate this information to my transport
stack?
Typically, one avails of routing information by not /requiring/ IP
protocols to be involved in the details of routing. Ie by layering
things correctly.
That's my prime reason for arguing against involving shim6
preemptively in the business of which local locator/source address to
use in packets it outputs.
