Two-legged desks that have a horizontal bar at the bottom connecting the two legs don’t exhibit said wobbliness, in my experience.

The Lumina team could consider this modification to add stability if that is an issue in their product’s usability.

I have a two-legged Steelcase with the design you mention, and it does wobble considerably compared to my four-legged one at home.

Raise your desk way up and give it a nudge - watch the monitor jiggle
