I'm glad they implemented this! Checking the photo of this particular feature, it seems the 1/4-20 thead is paired with another hole: https://www.notebookcheck.net/fileadmin/Notebooks/News/_nc5/...
I was very hopeful that the hole arrangeemnt would be for an ARRI pin-lock: https://www.arri.com/resource/blob/320202/04f5271d1d21f8c7db...
Referring back to the Nape Pro picture from CES, this appears not to be the case. One thing these 1/4-20 mounted ergonomic keyboard designs need is a locking mechanism that prevents the keyboard from gradually pivoting during regular use. For the Nape Pro, I wonder how feasible it would be to drill the hole into it's exterior?
If you're thinking of mouting these at the edge of a surface, then make sure your 1/4-20 mounting arms use the ARRI pin lock on that end. It's annoying when your keyboard pivots, but if the whole mounting arm pivots, then you might be in trouble (i.e, a loosened mounting arm swings 180 degrees down towards the ground, potentially damaging your keyboard).
Here are some examples of those types of arms from SmallRig:

And a clamp that has the ARRI holes:
