It's not acceptable to treat an unset Provider as if the convention is requested when the convention could be set elsewhere:

```groovy
public interface NewThing {
    Property<String> getSomeProperty()

// Unacceptable

if (!getSomeProperty().isPresent()) {
   value = "convention"
} else {
   value = getSomeProperty().get()
