The intent is not clear. How is the 2 to be formatted?

I fixed a nasty bug recently where a join of a list of strings contained a 
non-string in some cases.
If the str(bad_value) had been the default I would not have been able to track 
this down from the
traceback in a few minutes.

I'm -1 on this idea as it would hide bugs in my experience.
