I'm not entirely clear on why this was needed - The Matthews Correlation Coefficient can easily be used in multi-class multi-label classification and regression scenarios.

I'm guessing here -- because there are highly dependent uncorrelated datasets?

It's easy to give examples:

MCC is trivially extended to support regression and multi-label. See the implementation in http://grey.colorado.edu/emergent
