But on the other hand, the existing behavior is well specified and has been around since object.format was added. I'm not sure it needs changing. What's the harm in leaving it?
More complicated code. And maybe this behavior is less intuitive. It contradicts the documentation.
From the documentation of the format() builtin [1]:
"The default format_spec is an empty string which usually gives the same effect as calling str(value)."
From the description of the format specification mini-language [2]:
"A general convention is that an empty format string ("") produces the same result as if you had called str() on the value."
