Hi Bruno, I admit that I had ample opportunity to earlier comment on the proposed charter statement and didn't. So I don't re-open discussion now.
I trust you and Rob to interpret the charter item "New types of segments mapping to forwarding behaviour if needed for new usages" not as a statement allowing to get WG status for drafts offering solutions without prior describing the problems to be solved.

The work item is: "o New types of segments mapping to forwarding behaviour if needed for new usages." " (e.g., local ingress replication, local forwarding resources, a pre-existing replication structure)" are possible examples. Their purpose is to give a better practical idea of what "forwarding behavior" could represent. It's not a statement that the WG must deliver on "local forwarding ressources" . As a side note, regarding specifically "new types of segments mapping to local forwarding resources", I think one could argue that https://tools.ietf.org/html/draft-ietf-isis-l2bundles-07 could fall into this. But the discussion is moot as this work item has already been carried out by the IS-IS WG, independently of this SPRING charter.
