You are only responding to part of my email. As I said in my previous email: "There are plenty of cases where it's better to delay the child device's probe until the parent finishes. You even gave an example[7] where it would help avoid unnecessary deferred probes." Can you please give your thoughts on the rest of the points I made too?
