If you create a soft reference to an actor, then when you delete it, there will be a message that someone is referencing the actor. 
If you make a soft reference to an actor component, then despite the fact that the Reference Viewer will show a similar picture (depending on the level the actor is at), there will be no message, and the reference will break. 
Is this a bug in the current verification system, or was it originally intended?
It’s not cool when references can be broken so easily, when there will always be a warning in other places.
In any case, I think everyone would not be against such an option being in the engine.
