> As discussed with Neha on the ML.
> It should be possible to configure a topic to disallow unclean leader 
> election, thus preventing the situation where committed messages can be 
> discarded once a failed leader comes back online in a situation where it was 
> the only ISR.
> This would open kafka to additional usecases where the possibility of 
> committted messages being discarded is unacceptable.
