Giovanni, Hi!

Can you please elaborate on why you think the LABEL_SET having good labels
help in this context/argument? If the upstream-node doesn't guess right
(when picking the upstream-label), you'll get a PATH-ERR back with the
ACCEPTABLE_LABEL_SET. And this would happen for every setup request.
Wouldn't you call this a compromised solution?

Regards,
-Pavan
