Just finished reading the COMPRESS-118 and the 2 threads. I have to say that's a lot of content. :)
I have also read the Archiver and the Expander, and I do like them a lot. They have great abstraction, and the implementation for callback(CloseableConsumer and Finisher) do impressed me. In the threads someone was concerning that only few people use Commons Compress - I can tell that it's not that case : I'm in a big company in China and I can tell many teams are using Commons Compress. No need to worry about that. It seems other guys in threads are concerning about the real need for users. With enough feedback from users, everyone would agree with these high-level APIs. Maybe I can help you with it - just do some interviews to the users.
