I know it’s an old thread, but I recently searched for this and another mechanism @silverpill shared with me on fedi, which I think is also relevant to have in this thread (I’m using my own words here);
If a certain feature implies that a certain property is present on the object (and vice versa), then a check could be done for the presence of this property. This is only for these specific cases ofc. E.g. when a feature implies the presence of a collection (and vice versa), you could check if that collection is present.
