If the API is a minimal core, that sounds like a bug! However, I don't think that's quite the case, it requires that the consumer implement their own loggers entirely. What I'm thinking about is more of an spi/implementation separation akin to our loggers, but for transforming configuration bytes into a log4j configuration.
