I think my perception has changed in the last ≈ 10 years, to be more leaning in moxie's direction. It's hard enough to design something secure and usable, having to try and support all different implementations under the sun makes most federated approaches never reach any mass adoption.
Even though it's not a one-to-one analog I also think e.g the lack of crypto agility in Wireshark was a very good decision, the same with QUIC having explicit anti-ossification (e.g encrypted headers). Giving enterprise middle boxes the chance to meddle in things is just setting things to hurt for everyone else.
