> We still lack any way to communicate up and down the stack of an entire transaction, for example for debugging purposes. We should have a way to forward every single layer of the stack across each hop, and return back each layer of the stack, so that we can programmatically determine the exact causes of network issues, automatically diagnose them, and inform the user how to solve them. But right now, you need a human being to jump onto the user's computer and fire up an assortment of random tools in mystical combinations and use human intuition to divine what's going on, like a god damn Networking Gandalf. And we've been doing it this way for 40+ years. This violates the principle of encapsulation that the entire field of networking is based on, not to mention an massive security hole.
