Yes that would be great. Right now, there are many applications that use pinned certificates to communicate to servers meaning there is literally no way to see the data your own device is sending/receiving from the internet. It's an insane thing that should be banned.
There is one way, you can modify the app or the OS to change which certificate is pinned, ignore all certificate failures, lie about the certificate in use, log encryption keys, or not even ask the app whether it likes the certificate.
Not on iOS, of course.
