I think the explanation sounds reasonable too. Thanks. And many thanks to Brian for the review, and spotting important issues.

But there wasn’t any interest shown by the WG for doing it at this point. This lack of interest could be perceived as an indication that there are currently no RSVP-TE deployments that use an AS-ID in the ERO. The decision by the WG was to revisit this discussion-point if/when there is some interest from the community to use the AS-ID in the ERO.
