Sorry, if we were not specific enough in the Javadoc[1]. We would like
to replace `org.apache.logging.log4j.util.Supplier` with
`java.util.function.Supplier`, which is a source compatible change:
the compiler will just convert lambdas to another interface.

However this is more of a very long-term plan, which would probably
require an entirely new package name and `Logger` interface.
Effectively we should remove the `@Deprecated` annotation from our
code and just keep the Javadoc description.
