So why not leave the flexible interface here, and let users make
the decision?
In my mind, the flexibility is not always a good thing.
It is nothing but troublesome for the person who doesn't like
detailed setting. I don't know how many people want this flexibility.
I'm for Nikunj's desgin. Do you have any concerns?
