The weakness of mixed-mode is that it opens the door to forgetting to set a timestamp and creating a data-consistency problem where a reader won’t see correct data. If mixed-mode were limited to specific transactions, it greatly diminishes the chance of that happening in a random code path. We should add a flag to the transaction_begin API that allows a commit timestamp of 0. The write_timestamp_usage configuration basically goes away because there are 2 settings, ordered and never, and if you use timestamps, you’re doing ordered.
