 Review comment:
   I understand this. But as I said before, the default interpreter of new 
paragraph may not be the default interpreter of note. e.g. You can may get the 
config of `submarine` but the magics part could be `%python`. So I would 
suggest we first change the behavior of how to set the default interpreter of 
new paragraph. This is currently what zeppelin to do.
