These aren't very popular in the US so you don't see the dedicated "track saws" in stores here that are common in the UK for example. You can pretty easily buy a Kregg Accu-Cut which is a similar idea that you bolt onto your existing circular saw, but it's a little bit annoying compared to purpose-built track saws that are a tidier design and often plunge cut as well so it's simpler to start the cut. But you can also get proper track saws online, and I'll probably pick one up eventually to replace my Accu-Cut.
I don't think this is a perfect solution, getting cabinetry precision with a track saw might be tricky. But no one's doing that with a portable contractor table saw anyway. And the track saws are even more portable. I think the table saw concept is a better fit for larger, fixed tools, which I would guess probably have a better safety record than portables (larger table, cleaner environment, etc) even without sawstop technology. And I think it's more feasible to have good quality guards that will be less annoying on a fixed tool than a portable one, where they have a tendency to break off.
