They are. A proper one goes up and down with the blade. A saw without an in-built provision for that is a surprisingly tough retrofit [0].
A riving knife that doesn't go up and down with the blade is just a pain in the ass that gets removed the first time you aren't making a through cut and rarely gets reinstalled.

Even if you mass-produced a kit, it would require reworking some of the original parts, possibly at machinist level tolerances.
