I read through this a while ago while deciding on a design for my next dactyl-manuform build, and I'm unfortunately struck that in 5 years, we still don't have a good opensource trackpoint design. I wouldn't necessarily expect that one would pop up in a vacuum, except for these three data points:

1) The Cambrian explosion of 3D printed, custom, hand wired keyboard designs -- dactyl -> dactyl-manuform -> tracktyl (trackball based), entire companies build around kits and designs that have to be hand assembled, r/ergomechkeyboards, discord channels for things like bastardkb.com, etc.

2) The similar, if earlier days, explosion of trackball designs: see the long discussion at the Verge [0].

3) Equivalent popularity when available of trackpoint style pointers -- thinkpad keyboards and Unicomp clone Model M's with trackpoint built in (though with the cardinal sin for Linux use of not having a middle click option.

It seems like we're overdue for a good trackpoint module that I can build into the frame of a serious manuform style keyboard without having to use a 16mm piercing to extend the point past a full mechanical key.
