Yeah, you'd never change something as fundamental as moving up and down a line 
after decades of it working one way :-p.
My view is that while the arrow keys shouldn't change, C-n and C-p are 'expert' 
enough that a tweak to their behaviour can be justified,
particularly as it would be restoring an old and sometimes-missed feature.  But 
the Emacs maintainers will have the best idea of what their users expect.

The tutorial would need to change and say that while the arrow keys move point 
around physically on the screen,
the C-n and C-p keystrokes will always go to the next or previous line if one 
exists.  That would be something useful
for the tutorial to teach.

But apart from the question of defaults, a start would be to add functions 
next-line-logical and previous-line-logical.
These could then be bound to whatever keys you want without Lisp programming.
