Hi all,
In Log4j Core 2 there is a residual support for a logger named "root", e.g.:
<Logger name="root" level="INFO"/>
has the same effect as:
<Root level="INFO"/>
However `Configurator.setLevel()`, `Configuration.getLoggerConfig()` and
other methods don't support the `root` alias. Should we introduce
support for `root` to those methods or rather remove (in Log4j Core 3)
the residual support in the `LoggerConfig` class?
Note that being able to refer to the root logger configuration via a
non-empty string has its advantage: Kafka uses it for a REST API that
allows users to modify the configured log levels.
