Sometimes is not enough to get property's value, but it is needed to know if the value was actually set. This is especially useful when querying bool properties and having different defaults on different scenarios.
I think this needs to go together with the use, so that I can understand what exactly you need.
Is it because the bool property is "bool *" and thus cannot be set to (for example) -1 to indicate the default value?
