Is the <div> with class "views-element-container" around views pages needed?

It's unfortunate that this div+class that only gets added in some edge case scenarios and provides not much utility or context to themers.

But since @xjm (core maintainer) is not on board with the approach here, I propose closing this issue as a duplicate of #2721899 in order to combine forces and bring folks over that may still be using the patch and approach here to consider doing the "cleanup" of the divitis in a different, more sustainable way at the theme layer.
