Product Manager here. The answer is because we are tied to the ESR release cycle we have to release at a certain time (we are working on changing this). So we're shipping all the work that is done and stable. There is still work to be done to the front-end and as much as people want to trivialize it, it's not so simple. To make the changes we did, we had to rewrite a very complicated front-end with some code that has been there for 20 years and had entire systems built upon it. We are going to get to what the mockup showed. But we're going to build it right, and that means rewriting large pieces of our codebase. We'll ship the remaining stuff when they are ready.
