Bruno,


> - again draft-decraene-mpls-slid-encoded-entropy-label-id can be extended to support in-stack data if needed (this has been expressed multiple times) i.e. if post-stack data is found not to be enough.


Extending your proposal to support in-stack data effectively puts us at draft-jags-mpls-ext-hdr-00, with the backward compatibility issues that we’ve discussed. That is, IMHO, no longer in the realm of acceptable risk.
