We collectively set aside one time pads for the same reason. I’m sure the NSA or GCHQ will implement this for some practical purpose eventually since they use one time pads, but this concept is madness. It’s telling that proposals for information theoretic guarantees come from individuals and institutions utterly disconnected from mainstream theoretical cryptography research. That’s what it would take to propose something like this, because the modern foundation of cryptography is explicitly computational for reasons established decades ago.

Basically every reputable cryptography textbook rehashes this discussion alongside a nod to elementary complexity theory. It’s hard not to be cynical about the sincerity of research like this when there is an abundance of literature indicating that it’s conceptually untenable.
