Hi,

I've not read this draft and this may be a knee-jerk reply (or early to begin with this discussion), but why does this draft potentially request "updating" RFC8569 and 8609?

This proposal may be with insightful thoughts and useful for some applications. But why it needs to update the current bible, 8569 and 8609, we took much time to formalize them?
I know ICNRG is RG and not working in an SDO and it is not so sensitive to update any documents compared with IETF WGs, but except the case for correcting errors these RFCs should not be easily updated in the current situation.

In the near (or not far) future we may want to try to move this RG to WG. What we need to do now for making ICN research and engineering work more common or visible is to provide interesting/effective ICN services/applications not only in "a" research community but in different communities or preferably market. The chance to update RFC8569 and 8609 should come when this RG becomes WG at earliest, IMO.

In summary, my comment is it is better to consider the technical benefit without assuming the update of these RFCs.
Thanks.

Regards,

Hitoshi
