Not again, due!
Does DRI has some mentally wrong that cann't be fixed other than re-create?
Forking is not always the best thing.
A is suck, I can write batter one that does exactly the same as A, but
more clean code. So I go ahead and write new B.
Because B is new, so I have to fix fix fix fix bugs .
Long time after, B fixed all bugs and function the same as A, and , the
code is now as buggy as A's.
