Is difference in number of keystrokes (keychords) not fairly convincing evidence that, at the very least, vim results in less finger effort (and therefore lower risk of RSI) than other editors? Even if you don't believe that there's a speed advantage (it's entirely plausible that the delay from cognitive processing necessary to navigate vim's more complex interface dwarfs the speed increase of pressing fewer keys), I find it hard to defend the idea that pressing significantly more keys is not ergonomically worse than pressing fewer (controlling for effort variables e.g. using the Carpalx model[0]).
