I want a way for a 16 year old kid to make an awesome app and then distribute it to whoever wants it. Like back in the shareware days.
FWIW, I have a few ssh clients on my iPhone (Termius, Prompt, iTerminal) that came from the App Store. Termius even offers mosh. Why wouldn't they be approved?
Why is that even remotely important?
The only thing I can think of that would be a problem for that 16 year old kid (or alternatively, a sneaky black hat) is permissions. Maybe a color coded permissions model where green means can only access the most basic systems, yellow means could access some personal data, red being can access very important or practically all your data, you must trust them implicitly before installing.
