Review comment:
       The idea of the null checks, is so that you update just a partial part, 
e,g, if i only wanted to update say exclusive consumer, i wouldnt have to know 
all the rest of the config. And there for the update had to be a positive (e.g. 
it was set) change, to avoid an accident. Maybe could be that the approach here 
is to use "" empty string as a single its a positive change, e.g. theres a 
difference semantically in that its been set to "" its not null, and there for 
then could use that to clear it.
