I am just wondering when to choose the CoordinatorLayout over "Traditional" Layouts or are they (or at least some of them) going to be deprecated?

The question [ConstraintLayout vs CoordinatorLayout](https://stackoverflow.com/questions/40929686/constraintlayout-vs-coordinator-layout) already showed me that the CoordinatorLayout still has its right of existence.
I'd imagine that the FrameLayout is still a better choice than the ConstraintLayout when there is only one child View.

**But what's about the other Layouts?**

I am personally so accustomed to writing layouts by hand in xml so transitioning to the ConstraintLayout is very hard for me. Furthermore answers to this questions would really interest me:

**Does the ConstraintLayout have better performance then a nested Layout? If it is the case, at which point does this occur (which level of nesting)?**
