Without re stating the original message from the bank coalition,  which states this better than I could,   the client and MITM solutions are not practical in many situations.    Also they do not provide the scope, depth or detail that is utilized with today's solutions.

What exactly is the problem you are concerned with? As I've pointed out previously one can still log the contents of TLS protected
connections: you do this at the client, or with an intercepting proxy.
What information does this not get you that you need on the network?

Do  Akami, Cloudlflare and Google magically not have these problems?
