I just checked it out on my Nexus 7 and I'm not very fond of the fact that desktop apps and Ubuntu Touch apps are all mixed in with each other now. I liked each type of apps to have its own scope and also hoped for Anbox apps to get their own in the future. Also, it's not intuitive that you have to swipe/click the Ubuntu icon to get the launcher to show up in the first place, but I assume that's temporary.
It was always the intent to make legacy apps easier to access by combining them into the main apps view. If Canonical was still building Ubuntu phone and Unity8, this would have made it onto phone images almost 2 years ago.
How is it not intuitive to swipe or click on the Ubuntu logo button? This has always been the way to get to the scopes before. It is not temporary at all. It is how unity 7 works, and it's how unity8 has always worked. The only difference with the new drawer replacing the dash, is that it is not always shown, because to do so goes against the ideals of convergence.
Also, it is called the app drawer. The launcher is the small vertical bar on the left, which some also call a dock.
