They did look into putting a trackpoint in there, but there wasn't enough depth in the keyboard cover to support it. Making it work would take re-doing the whole bottom shell (apparently).

I'm tempted to make a thicker bezel so the screen won't close all the way anymore. Pick up the room for a trackpoint by going wedge shaped! (edit, obvious downside: the screen would be a lot weaker when closed)

Yeah, probably not worth it for them although their design gives me hope that at some point there will be an alternative keyboard to choose from. On my keyboard (Thinkpad T14) trackpoint seats flush or even slightly below the keys but that keyboard has quite a bit of travel and it does touch the screen on regular basis when closed.
