When you proposed the idea at EuroPython, it seemed reasonable but we didn't go into the pros and cons. The downsides include breaking tests, changing the output of report generating scripts that aren't using string formatting, and it introduces another inter-version incompatibility.
Yes, I agree that the change has potential for breakage; it's a change that probably would have been unacceptable for Python 2.7; for Python 3.2 I think there's a little more scope, since 3.x has fewer users.
+1 for making the change to 3.2 +0 for 2.7
-1 for 2.7. -- Regards, Benjamin
