Dimension Exclusion

Why is there a need for ‘dimensionExclusions’ as a separate field? As per my understanding, we can simply exclude the dimension in the ‘dimensions’ field. Does it solve any special purpose?

I believe it’s for convenience, in that you can leave the ‘dimensions’ field empty, allow Druid to automatically discover the dimension names, and exclude any dimensions specified in ‘dimensionsExclusions’.
