As I said during the 109 meeting, I support adoption.
We have at least two immediate use cases for this:
- Ability for customers (and maybe peers more generally) to prove
  ownership of their ASN
- Ability for customers-of-customers to signal to us which TE/Anti-DDoS
  actions we should honor via communities for their address space

As I mentioned during the meeting, the first of these probably should be
exchanged outside of repo publication; the second needs to be published
in the repos so that direct communication between unrelated parties need
not be required.

As such, I think a primary focus for work on this should be to flesh-out
how in-/out-of-repo should co-exist, and how validation should be done
in each case.

Cheers,

Ben
