Just resource allocation issues. E.g. imagine having an existing kafka cluster with one machine spec, and getting access to a few more hosts to augment the cluster, which are newer and therefore have twice the disk storage. I'd like to seamlessly add them into the cluster, without having to replace everything en masse. Thus, it would be nice for the newer ones to take proportionally more load based on the relative storage available, etc.
