I think having rating agencies for ledgers might actually make connectors
too reliant on those ratings, as opposed to their own due diligence. How
would a connector price the risk incurred by dealing with Bank of America
or Bitcoin? Similar to how they price different assets they decide to
trade: historical data, knowledge and understanding of the systems/markets
they're dealing in, reputation, self-funded insurance, hedging, etc

Agreed with Ryan that this shouldn't be part of the core protocol either way
