given that they're a shrinking rarity, would it not make sense to

Nick and all,
Thank you. What you all shared/discussed is very useful info.
Almost all RS's are transparent these days. Usually IXPs go to
lengths to ensure that the RS ASN doesn't appear in the AS path.
Good to know that. Well, that
in its ASPA as a "Provider".
