Yii - how to replace root classes?

Question

Yii

Good afternoon, colleagues! I am developing a project on Yii1, and I saw a lot of interesting goodies in the Yii2 code that I wanted to have in my project. For example, the static className method from the Object class, which I want to add to the Component class accordingly, the load, formName methods from the Model, and some others. There was a question about substitution of root classes. I want all my classes to chain-inherit from Component instead of CComponent, I'm thinking about using a trait so I don't have to rewrite a lot of code. This is the right decision?
