Curious about new 2019.3a10 Debug key ?

Unity Engine
1

When converting my project from 2019.a7 to 2019.a10 I got a error regarding Needed to setup a Debug key in : Edit->Settings->Input

As i could not find any button to set I added the new Input package.
The error is gone and i see that the Debug button is set to the left ALT

I also noticed when starting the scene a new Debug gamobject was added.

I can’t find anything in the release notes so what does it all mean ? Where it is used for etc ?

Update: it is a combination of two Debug keys: [Left-CTRL] + [BACKSPACE] in the Game Tab while in PlayMode.

It will bring a hidden Canvas with some prefab controls that has something to do with testing your own render pipeline of some sort.Its hard to find much info about it. so ill ignore it for now.
