The deprecation was introduced as a requirement of semantic versioning:
"Before you completely remove the functionality in a new major
release there should be at least one minor release that contains the
deprecation so that users can smoothly transition to the new API."[1]
However in January this year (cf. [2]) we decided that we will not
release a Log4j API 3.x version in the foreseeable future. We will
only release a major version of our logging backend Log4j Core. I
guess this means we can remove the @Deprecated annotation. Personally
it bothers me too to introduce all those `@SuppressWarnings`
annotations.

While we chose the same Java baseline as Spring Boot 3.x (Java 17),
Log4j Core 3.x will be easier to deploy, since it will just require
the replacement of a runtime dependency.
