@heymatthenry took a shot at creating a beta issue for Banner based on items we discussed in this weeks Dev sync.

Feel free to edit and add any items I might've missed.

@mejiaj Awesome, thanks for doing this! Added one thing, but otherwise I think it's good to go (understanding that we aren't ready to incorporate interoperability tests yet).
