Do we have an example workflow of using a multi-sig transaction, which has a payload to support KYC for complying with regulation laws, that we can use to evaluate how CS would work? This workflow demos integration with OFAC service, has a validity interval, responds with error message, etc. Perhaps, a simple concept of how CS would work is not even going to meet our needs, in case the SEC requires deep checking, detailed reporting, etc. This con is basically- "do we understand the problem".
