The Angular team has made significant changes under to hood to what AOT generated code looks like. These changes have gone on to diminish the size of the generated code for your components by around 60% in most cases. So it would have apparently higher saving for the complex templates.
The Angular University informed that they have pulled animations out of @angular/core and into their own package. It means if you are not using animations, then the extra code will not end up in your production bundles.
