Expand Power BI Visuals API to get Column Descriptions from semantic model

I am developing a custom visual and my desire is to get both columns and their respective column descriptions into the visual. 

I would like the Power BI Visuals API to be expanded to inlcude a 'Description' attirbute to the 'DataViewMetadataColumn' property. I dont know if the column/measure descriptions that can be defined in the 'Model View' of Power BI desktop are exposed to the Visauls API, but that is the data im looking for.

Please let me know if there is some other forum or place I should make this request.
