On: Fullscreen mobile modal: how hard can it be?

iOS does not push modals onto the navigation stack by default.

To be fair, iOS doesn't have a universal 'back' button, so you wouldn't reach for it to exit a modal anyway.

Sure, but the general guideline for modals is to have a "Cancel" or "Done" bar button item somewhere to exit. This is a different action than popping a view controller off the navigation stack.
