This wouldn't. Graphical interfaces lack precision, clarity and safety. Try
to hit a pixel with the mouse. Try to formalize "two images are same". 

Being graphic is not an advantage, it is a disadvantage. Raw visual input
is just too much to handle for any computing system, human brain included.
This is why certain forms of noise reduction evolved, starting from
primitive pictogram and ending with highly specialized scripts. Ada is such
a script.

The point is, it is a novel form of expression, which may justify the
interface being graphic. (E.g. to show the package specification and body
in two separate windows.) Not the reverse.
