I like the concept.
Wording-wise, there is room for misunderstanding in the current version,
2.2.1:
2.2.1. Packet Filter Considerations
The packet filter should be designed and specified in a way that:
o only affect link-local BGP traffic i.e. forming part of the
control plane of the system described, rather than multihop BGP
which merely transits
it says "link-local", but what it wants is not "fe80::" but "the prefixes
the intermediate network uses for on-link peering" (plus, maybe, fe80::).
So maybe "only affect *on-link* BGP traffic"?
