Hmm these explanations have always seemed to me as giving reasons why the 
default behaviour of POV is wrong.

How about having a camera block where you specify the vertical FOV, and the 
default horizontal FOV is automatically calculated to give square pixels. 
But you can override it if you want.

That way would fix #2 about "panoramic" shots keeping the vertical FOV while 
you expand them.  It would also fix #3 because people could still render 
non-square if they really wanted.
