You're right, it's not a coincidence. The track record of standards-body-driven cryptography is wretched. It's why we all use WireGuard and not IPSEC. TLS 1.3 is an actually good protocol, but it took for-ev-er to get there, and part of that process involved basically letting the cryptographers seize the microphones and make decisions by fiat in the 1.2->1.3 shift (TLS 1.3 also follows a professionalization at CFRG). It's the exception that proves the rule. It's contemporaneous sibling is WPA3 and Dragonfly, and look how that went.
