Oh no, Dad's old all-steel table saw that was designed and built to be repaired, and which has the same tolerances as a "precision tool" today, doesn't have bluetooth to pair with your iPhone? Guess you'll just have to toss it, then.
Unfortunately it probably also doesn't have all the safety features like a riving blade, either. That doesn't mean it's useless, but it does mean it needs more care to use it and novice woodworkers shouldn't rush in blindly.
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.
Someone in my town started a tool library. It's a collection of tools that people can borrow and then return. At the moment it's just in a storage locker. Some tools can be obscure and rarely used like a toilet wrench for the "spud nut" for the gasket that's under a toilet tank.
I'd love to go through all those "useless" tools.
