Review comment:
Which other class will use this method in the foreseeable future? Once it
becomes necessary to use this method at different places I'm ok with making it
public. However, at the moment, this should only be used by the `MiniCluster`
and, hence, let's move it there. Moreover, this would further increase code
cohesion.
