I will respond to your specific concerns that I have never been in a professional audio setting where they did not have every form of connector I've ever needed, and they are particularly well prepared for Apple devices. I have never been without a needed cable in a pro audio environment, or even an amateur one. As far as the headphone jack is concerned, I feel badly about the average non-professional consumer who will run into situations in an old car with their Android buddies, or DJ at their friends party, and forget a cable, but I'm not worried one bit for professionals.
Re: pro audio - yeah pro-audio when you're in a studio of major concert hall but I'm not some headlining DJ, I'm just a guy who wants to hear his music at parties, bars and festivals. In these cases you need to bring everything you want to use including your own RCA cables and patch cords because you never know.
