For now. Software is constantly changing. Plus, even my very old gearvr had color pasthrough.

And, when you consider that valve is partially putting out this device to stoke vr/ar/mr enthusiasm, I would have liked to try a headset with great pasthrough. I tried the apple headset right as it came out in a store, and the headset was awesome, but lived in a closed wall garden. The passthrough on it was awesome. That xr keeps taking steps backwards is tragic every single time.

I guess now I know what it must've been like in the 80s when vr was this cool tehcno fantasy that went nowhere until basically palmer lucky spits on floor.

Edit: i forgot to really answer. Because passthrough is part of vr. Also because it's cool. Also because it's still novel to me and I want to play with it. Also because maybe I would have made something with it. Also because backwards progress is sad and annoying and feels bad.
