No, it's not a deal. It's only about learning IMHO and that's already be great.

In fact it's such a "bad" deal that I replied a bit in depth. My goal isn't to bring the project down, heck I'm even envious about being able to do all that, but rather that people curious about VR don't get confused. This is nearly a decade outdated and there are better open solutions, e.g. Lynx or even Meta Quest 2 without account IMHO.
