I would also propose to bind #2076 to this task as a cleanup job.

The whole log4j-slf4j-impl should IMHO be removed from 3.x or at least reimplemented in terms of log4j-slf4j2-impl.

I am currently working on:

• log4j-mongodb4

so I marked them as done to prevent collisions.

Related to this are PRs that remove additional dependencies from log4j-core:

• Split off YAML configuration into its own module #2142
• Move o.a.l.l.core.parser to samples #2154
