Well, you can turn warnings or off using a command line flag or by making calls into the warnings module, so everyone who emulates a REPL can copy this behavior. I'm not worried about that.

One can use the commandline switch if one wants to.

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.
