TYPO3 Core

I want to suggest or upvote to integrate this container plugin https://github.com/b13/container/blob/master/README.md into the core as this is a universal feature that is missing in the core currently (at least an easy implementation is missing).

A container content element that can wrap other content elements provides a solution for a lot of design situations.
As this extension already implements all core features like localization, workspaces, etc. I would like to give the implementation of this into the core an upvote at this point and for my own current project implementations I would like to know about these future plans if there are any.
