HBASE-27109 has been merged, which is the last feature I want to land in the 3.0.0 release.
The road map is to make 3.0.0-alpha-4, which is the last alpha release for 3.0.0, and then cut branch-3, focus on stabilizing and make two beta releases, and finally cut branch-3.0 and make the final 3.0 release. Shout if you still have other things that want to land into 3.0.0 release, as once we cut branch-3, we will hold on the committing of big features so we can soon make the branch stable enough, and prepare the final 3.0.0 release. Thanks.
