Robert. I do not assume about 100% traffic in the given network is SR. I only assume that the operator prevents any traffic paths from using SIDs that have been associated with the CS topology and its resources (e.g., steering all non-CS traffic across the default topology), be it intentionally or due to some transient condition (FRR, micro-loop avoidance etc.).

Well ingress or egress interface queue is a physical resource last time I checked. Leave alone zero view of intra chassis fabric issues and drops. Then last but not least you are making a huge assumption that in the given network 100% of traffic is SR .. Good luck !
