Jared,

​In the past things like that were also actually solved within single
release by automatically generating this line of "missing" configs if no
other policy was configured. However for this specific case I am not sure
what does it buy you in practice. Maybe consistency across BGP
implementations.  ​

​Well if both drafts can solve the same problem maybe there is a room to
discuss it and pick one to go forward with.
