A good, if a bit strange, example. A CPI logger wouldn't need to log the same thing as an access logger, but the producer need not care about who is consuming the logs. Consumers might even want to see both and, given the design, can have both.
Certainly logs lose their value if they are wrong. And either approach is ripe for getting things wrong. But the idea is that the consumer is more in tune with getting what the consumer needs right. The producer's assumptions are most likely to be wrong, fundamentally, not having the full picture of what is needed. What is the counter suggestion?
