Matt, PJ, shall we migrate `log4j-scala` from sbt to Maven?
`logging-parent` 10.0.0 ships a great deal of convenience for build+release of Maven-based projects. I have already migrated `logging-parent`, `log4j-tools`, `log4j-transform`, `log4j-kotlin`, `log4j-jmx-gui` to this shared infrastructure. Unless we do certain tricks in sbt that are not possible via Maven, I would like to match `log4j-scala` with the rest by migrating it to Maven too.
