You don't havew to use the plug-in you can still carry on working the way you are familiar with. The plug-in was a new feature that there had been quite a demand for and it is still a work in progress. However the fundamentals of the program work exactly as before so you could still drag and drop files. You would of course have all the extra new realtracks to drag and drop.
The VST plugin was the main selling point of this upgrade for quite a few existing users and it doesn't work, so there is no need to discount the people who purchased this upgrade for the VST plugin as if they are irrelevant and should just pretend to be happy to pay for something that is " still a work in progress".
The VST should have been advertised as a "work in progress that is unusable as a DAW plugin" if that's what it is, instead of a "new and exciting feature".
