What's the Improve
Currently, react app container dom document.getElementById('root') has only contents' height.
Current
↑dom height not covered browser screen empty space.
But generally, I suppose majority users will remove existing App component stuff(code, logo, css), and then start write their own component.
At that time, if document.getElementById('root') has fullscreen width/height by already, initial develop feel is quite good I think.

I'm glad anyone in the maintainer has read through,
If this change is attractive to many users, that's would be great to merge and I'd like to contribute to improving create-react-app
