I don't think that it would be a problem as long as it were properly designed (and to be honest, Kildonan isn't the kind of station that someone who was severely mobility limited wouldb likely be using by themselves).
It's more of an issue that it needs to be able to be proved working remotely or else trains would need to slow down anyway.
Having it "fail safe" is the way to do that. Bulb lit = no stop requested. Bulb dark = failed or stop requested. And some kind of feedback on the button itself.
Unsurprisingly the Swiss have something like this
I'd also like to see bus style stop buttons on trains rather than having to find the guard.
