--------------------------------------

bq. So it looks like we actually want --add-broker (and transfer some load to 
it) and --decommission-broker (and transfer its load somewhere)?

Right. 

[~Dmitry Pekar] We would like to avoid adding more and more nuanced options to 
the partition reassignment tool that is already too complex. I would suggest 
taking a step back and arriving at a few simple options that would cover all 
use cases. I think that all we need is a way for users to add and decommission 
brokers and the user's expectation would be that the tool comes up with a 
correct assignment that leads to roughly even distribution of partitions as per 
our replica placement strategy.
