You are assuming that the display swaps between the two quote 
characters.  This might not be so, depending on how the display works.

There are several implementations of the Unicode algorithm, and they all 
differ in some hard cases.  So the goal of gettin the text displayed the 
same everywhere seems to be impossible to achieve anyway.  Given this, I 
don't see any disaster in having another slightly different implementation,
provided that we think it is a better one.  (And it really isn't so hard
to come up with a better implementation, believe me.)

Of course, strict conformance to UTR9 should be a user option.

Not necessarily.  I was talking about cutting and pasting within Emacs, 
where the OS isn't involved at all.
