U7 Composition Properties?

Excellent package!
Does the current NuGet version support Composition properties from Umbraco 7.2+? 

I see that there is a Compositions section in the def.config file which properly lists any selected DocTypes, but none of their properties appear in the Model except for the Master DocType (if any). 

Not sure if this is a bug, missing feature, or an incorrect implementation on my end.

Thank you!
