But I don't want to make all log levels go to stdout. Just DEBUG and 
INFO. But this would be a workaround.

The main question here is why does Python deciecded to make all logs go 
to stderr?
Maybe I totally misunderstood the intention of logging.info()?! Isn't 
this the "usual applicaton output"?

If not, what messages should go into logging.info()? Can you name me 
some examples?
