Is this empty room at the end of 'Failing Forward' a dead end?

So I have the red gun and I am in a tunnel with a yellow light, and a laser switch with a green locked door far away.

The tunnel

I walk closer to the locked door. Thanks to incredible timing and agility, I pass through the locked door.

I turn back and have a last look at the system I have just passed.

This is difficult to pass through without a cube

It seems I am in a room with no obvious hidden door, and really nothing to do.

Is this room a dead end?

Solution 1:

Yup, supposedly the developer put it in so there is a place to add more content.
