Eh honestly frameworks are unique, differentiated and practical. I just can't live without a trackpoint.I don't use the pointer much anyways, so the convenience of just having it right there on the home row for cases when I do is irresistible. I love it so much that my desktop doesn't have a separate mouse, just a TEX Shinobi keyboard (which has a trackpoint). My main laptop, X201s with cool chinese CPU upgrade also doesn't have any pointer input other than a trackpoint. I think you can see why I am hesitating to switch to a device without one, even if the repairability, future mobo upgrades, and "internal dongles" are very appealing.

And as for the dying breed, I don't think that's necessarily the case. There are a lot of questions & requests about it on Framework forums, r/framework and such. It's just that it would require a serious chassis redesign which is insanely expensive.
