We won't be changing away from log4j.
Additional info: Recent versions of log4j2 provide a logging facade similar to SLF4J and do not rely on a specific implementation. Please use any of the available Log4j adapters to route logging to the logging implementation you use. You can also use [log4j-over-slf4j](https://www.slf4j.org/legacy.html#log4j-over-slf4j) to route logging through SLF4J.
personally i'd advocate for JUL because it's vanilla, off the shelf, and pluggable as well. but that would require someone doing the lifting and i don't foresee that happening
