There's a vocal minority of people (I count myself in) that really, really like trackpoints and would love to have a Framework laptop with this kind of pointing device. I think it would be more productive (or perhaps its wishful thinking on my part) for you people to say something like "we need to shave x mm from the Thinkpad one to match or requirement" or "we need x dollar to hire someone / to let our product engineer spend y amount of time on this project.
(and I'm of course ignoring the dozen or so patents that probably prevent you to implement this... but I really really like trackpoints)
