I think that (like me) you overestimate the size of population looking for an opensource trackpoint design. For your trackball example there's the Ploopy [0], but even there we're still dependent on something like the PMW3360 sensor board (which afaik isn't open). I just can't picture how designing and manufacturing a new trackpoint board from scratch - one that competes with the excellent Trackpoint IV modules that are used in the also excellent TEX[1] trackpoint keyboards - would ever be profitable, or worthwhile given that there are patents and licensing issues to deal with. If, OTOH, you're just after a trackpoint module and a stem extension that works, check out the Sprintek SK8707 on Jonas Lang's Trackpoint Groupbuy discord [2].
