Session Component not available in CakePHP 3.4.7

I am just start working with CakePHP 3.4.7 latest version. When i am start making my own Components, i am totally strange about that CakePHP 2.x have separate Session Component which i can easily include in my component using $components = ['Session'] properties but this component is not available in CakePHP 3.4.7 latest version.

So what is the problem? is that core developers decide to remove this important component or anything elseā€¦?

most of the answer to this is here and why they didnt make component as facade? im not sure but probably because its additional pointless code when you can just do $session = $this->request->session();
