Which was one of the reasons why I send the my message to 
python-dev@python.org I would argue however, that this is not 
a new feature, just a fix of a bug which has been overlooked for 
long long time. I don’t think I am changing API, just fixing 
a bug which made urllib2 fail to login into many sites (yes, they 
are broken and not following RFC). I am not sure I am right, but 
I guess it is valuable to discuss it.
