English spelling is a terrible mess anyway, full of arbitrary contrivances and exceptions that outnumber rules. Why receipt but deceit? Water but daughter? Daughter but laughter? What is the logic behind the ough in through, dough, and cough? Instead of trying to get the letters right with imperfect tools, it would be far better to loosen our idea of correct spelling.
