 Review comment:
   @dongjoon-hyun Ok so that is what I also concluded :) I can do that, it 
looks fine to me, the only issue is that this way we open the door to adding 
arbitrary options there. Initially that was what I didnt want to support, thus 
I used that the flag to make defaults unchangeable (defaults usually have fixed 
values). 
   But we could be flexible here for simplicity reasons,  so I will change to 
what you suggest.
