Saving Data In Join Table

As per Mr. Qiang in this post. In YII 2 there will be no MANY-MANY relationship, furthermore separate model class have to be created for intermediate table. Instead why not take the approach of pivot table like one in Eloquent ORM like this. I think in my opinion this is much more elegant way to deal with intermediate table than what YII currently have and proposed version in YII 2 AR.
