Look at the bleed left and right, that's what I don't see the need for!

Personally, I think the next development in bike headlight optics should
be to purposely add lateral beam width, and with an upward component. I
want cutoff straight ahead, as with automobile lights. But if there were
a little more light thrown (say) up to the right, it would help on a
right turn into a driveway or tight street intersection that was unlit.
The upward component would be to compensate for the bike's tilt during
the turn.

A further benefit would be a brighter light directed toward motorists
approaching a stop sign as the bicyclist proceeded with the right of way.

From the video of descending Highway 9 with an Oculus, you can see that it has the lateral and upward light throw which light up around the turns. Racers at RAAM loved this on the fast descents and curves where the support van (mostly Sprinter type vehicles) can't keep up. It also has more sideways light, shining sideways out a side street when facing forward at an intersection, and downward on the road immediately below and on your bike and feet, than any other light that you might find to compare with. No problem seeing your bottle cages at night with an Oculus on your bike. To car drivers, it looks more like a car headlight pattern on the road, that they can't see is just a bicycle.
When coming up on other bicyclists from behind, they also sometimes get fooled into believing it could be a car approaching.
