So then the transition strategy is something like:
version N: Add formatting flag which uses {}-style formatting on True and %-style formatting on False, which defaults to False version N + 1: Deprecate False value for formatting flag (all code should start specifying flag=True) version N + 2: Raise error on False value for formatting flag (all code must specify flag=True) version N + 3: Deprecate formatting flag version N + 4: Remove formatting flag
