Well, in order to justify the hassle of invalidating existing implementations of the draft as it stands, I suspect there'd need to be sufficient examples of real-world problems with passive BGP 'readers' to get consensus in IDR to change.
This is exactly why people shouldn't implement drafts except possibly as a private in-house feasibility study. There has been a huge inflation of the status of various IETF documents, to the degree than BGP today apparently isn't considered mature enough to be an "internet standard".

BTW, I find the notion that there is a new attribute that carries 32- bit AS numbers while at the same time the original AS path can either hold 16-bit or 32-bit AS numbers depending on the capabilities of the peer rather strange. Why not simply keep the current AS path 16 bits and create a new 32-bit one?

And what's with that "octet" thing, anyway.
