Sure, I can add it to showcase the usage. The percentage threshold sounds better to me as it involves analyzing both the caller and the callee.  One thing I am not clear about is what to consider "a caller".  I think it should be the first parent that is `IsolatedFromAbove`, but I am open to other ideas.
