I think this is the right step forward and enjoy seeing CEXs self regulate in order to gain favor with consumers.

However, other liabilities related to the operating business are not included here (e.g loans from traditional finance or PE/VC forms). This could be overcome if the CEX sets up it's organization to only give seniority and secured debtor positions to each depositor to ensure that, in the event of a bankruptcy, the depositors would get their money out first.
