You can already do this to a considerable extent, and a couple of handwriting font generators support the notion, but it’s still fairly manual. In order to do it all realistically, font formats just aren’t the right primitives, and I doubt they ever can be (though… hmm, wonder if the HarfBuzz WASM thing might be applicable): you need something more like stylus data, e.g. a sequence of {x, y, tilt, pressure} for every 5ms, which you can then jitter and vary realistically.
