Public vs internal types for UDFs

-- Edited, reworded because I was mixing up concepts ---

Hi,

Would you consider changing the types whose public methods are considered applicable for ExcelFunctionDoc etc from GetExportedTypes to GetTypes, so public methods from internal types are considered as well?

ExcelDna itself allows UDFs to be in internal types, so the behavior would be the same.
I myself have a class hierarchy that should not be completely exposed as public, hence my question.
