If you look at org.apache.logging.log4j.core.lookup.StrLookup, you can see the interface and its impls in the same package.
For org.apache.logging.log4j.core.Layout<T extends Serializable> though, the impls are in org.apache.logging.log4j.core.layout. Shouldn't we move Layout to org.apache.logging.log4j.core.layout?
