Yeah. I was looking about a year ago and it appears that this project was operational then. Pretty sure I never came across it. Maybe this initiative will make it more discoverable...
Edit - And it creates a bit of a conundrum for a project like the one you cite, too (was just looking at your link). You want to support new developers, but you end up with a relatively long list of supposedly easy to attempt issues that no one takes.
