It's a really good question, and one that I'm probably not qualified to answer since I enjoy my cider just fine without sulfites. Text book answer is probably yes.
So, you really just need to ask yourself, do I prefer to do things by the book, or do I just do whatever I feel like doing, or is this question worth an experiment to find out whether it really makes any difference? Of course, it is your decision, and no one else's.
I imagine and hope that someone else will chime in. I truly hope that I'm not dissuading others from sharing their opinions. All opinions are valid, especially in areas like this that might not be very well explored, at least not on the home cidermaking scale.
