The idea that NIST is trying to weaken cryptography by regularizing TLS intercept at banks is tinfoil hat stuff. Not only were banks already doing this, but they literally tried to halt TLS 1.3 and re-add RSA key agreement to keep doing it. NIST is trying to minimize harm here.
I mean, it's not that tinfoil hat as the DRBG debacle showed.
But I'm not talking conspiracy here, I just feel like providing a 5 volume tech manual on how to do pervasive monitoring under TLS1.3, no matter their stated justification, is antithetical to their purported mission.
