Do you see any reason why we wouldn't always use get document by id? I admit I wasn't responsible for the hash router implementation so the fact that there is all this query selector stuff just for this case sort of surprises me. I will do some forensics here but the native DOM behavior seems to be restricted to ids so I don't see benefit in applying a general selector and trying to restrict it to fit.

I prefer to use document.getElementById, but since there might be cases in the existing project where a selector is used (even though it's not documented), I was a bit hesitant to change the code.
