Hi Samuel/WG, Thanks for following up on this point.
As I had mentioned in my review, it is problematic to specify anything concretely for Algos 2 to 127. This is because they are subject to what may be specified by future documents (i.e., in LSR WG). Therefore, from a protocol correctness perspective, please consider making only suggestions or bringing up the idea that SID filtering can be applied to those algos, but leave it to future specs to actually specify such behavior. I hope you can consider this as well.
