Hi everybody, Besides the enhanced NDC, there is another SLF4J 2.0 feature I don't really know how to deal with:
https://www.slf4j.org/api/org/slf4j/spi/LoggingEventBuilder.html#addKeyValue-java.lang.String-java.lang.Object- These key/value pairs in the `LoggingEventBuilder` seem to be separate from the MDC, so we can not inject them into the ThreadContextMap. The reference implementation of SLF4J adds them to its `LoggingEvent`, which suggests that we might create a new `Slf4jMessage` and add them there. The problem would be how to format such a message. What do you think? Piotr
