I'm loving the Property Type Converters shipped with 7.6. They're a fantastic addition!

However, I'm wondering if they can be used in Macros? Perhaps I've missed something somewhere? Or is it an oversight in the Core?

Take the following example (where "picker" is a Content Picker):

var picker = Model.GetParameterValue<IPublishedContent>("picker");
var udi = Model.GetParameterValue<Udi>("picker");

In this case picker will be null, however udi will have successfully returned the UDI. Of course, once could just simply do var picker = Umbraco.TypedContent(udi), but I was hoping to make use of the Property Type Converters for less code.

The above example is on Umbraco 7.6.5
