It's a vestigial organ from the BGP-3 to BGP-4 transition, and a poorly specified one at that. We shouldn't include its use in specifications, particularly where discussing aggregation. > > The only place its discussion would be relevant is as part of *de-*aggregation of a prefix. > I have to disagree with this position. I am more than happy if you want to push out a spec that updates RFC1997 and RFC4360 and drops the atomic-aggregation conditions and applies the same considerations to this document as well. But having current specs that say “do <this> with communities and extended communities and do <that> with large communities” is bonkers! We should be consistent here and not just deliberately generate inconsistencies here - that is not doing anyone a favour.
