A change limited to the interactive interpreter would be meaningless for 
everyone who works at a simulated prompt in a gui program running on 
non-interactive python, or running user code under supervision in 
non-interactive python.  This includes both modes of Idle (default and 
-n).  I presume this includes nearly any other alternative to the 
console interpreter.

On Windows, the actual Command Prompt interactive interpreter is a 
wretched environment.  I only use it to start Idle on repository builds 
and to check whether Idle does the same thing as the console 
interpreter.  I suspect that many users on Windows never see the console 
interpreter, just as they many never see a command prompt command line.
