This SWIP handles the simplification of the addition of extra information needed in order to have better eventual consistency in a neighborhood. Instead of adding information - we reduce the number of fields. This is obviously a breaking change. The other negative side effect is that we'd have to keep the extra Sum bytes on the indices in order to avoid an extra chunk lookup for every chunk we Offer. Due to this I suggest to lower the Sum length to 8 bytes (32 mb extra data in the specific index for a ~4.1mil chunk reserve. 16 bytes would be 65 megs, none are deal-breakers).
