Does that mean it should be deprecated in the docs?

I just downloaded the most recent docs and they describe % under "Old
String Formatting Operations" and say "The formatting operations
described here are obsolete and may go away in future versions of
Python. Use the new String Formatting in new code."

So for new users, str.format() will be _the_ way.
