In this case official would be like Oracle release new version of Java with statements in release news like "We continue to have significant memory bloat in standard Java Collection data structures. We added a higher overhead and slower G1 GC which will be default going forward. In Java 9 we also hope to break many user programs which depends on Sun internal APIs" Now this sounds ridiculous because announcement of major product/feature are suppose to highlight advantages just like Go's new GC announcement blog. Tradeoffs are discussed in mailing lists and bug trackers.
