I do not want to alienate users in going from 2.x to 3.x. From a user’s standpoint where all they have done is created their own Appender Plugins or are simply using Log4j they should not have to recode their application.
This is especially true with the API. Applications that simply use the API must be able to only change the dependency. Applications that implement standard Plugins (Appenders, Layouts, Filters) should only have to recompile. User’s who customize more than that should expect to have to modify code.
