Gert:

How do you characterize network management?  Traditionally network management has been viewed in the IETF in two streams:  monitoring (active or passive) and configuration.  

What parts of these features do you think the IRS system needs to avoid?

Tom,

It is confusing to understand whether IRS belongs to a new network management plane or if it's more of a control plane extension. The draft wisely avoids this classification.
To me IRS appears to be a completely different beast which should best be  characterized as 'Network Programming Plane' NPP. 
It neither aims to do full provisioning (as a management plane would do) nor aims to replace routing (as a control plane would do).
Hence we better name the baby NPP -- thereby avoiding any linkage to taxation.


Gert
