Yeah there are two issues here. The timestamp element which I will not use at all, and very fact that there is an ordering to them. He mentioned a few rare edge cases that it wouldn’t be reliable implying to me that in the other cases it is reliable.
Those edge cases, the ones you laid out, are not ones we are concerned with, but we still would not rely on it at all if not for that we can indeed recover what we need from the dcp/connector if something truly very strange should ever happen (like CB version 8 changes the CAS system)
@pvarley please let me know if this is offbase.
