Given that you quoted Jason Donenfeld quite a bit I propose that you actually ask him for his design criteria. Because what you seem to propose is adding more and more variations to OpenPGP. I discussed this with Jason before and he's a strong advocate of less choices and strongly against algorithm agility. And I agree. FWIW I believe the pros and cons of the different AEAD ciphers are of very minor relevance, yet the algorithm zoo is a big downside. From what I know openpgp has still not published a standardized AEAD. My proposal would be to choose one and only one AEAD and declare all other algorithms as deprecated. And which one almost doesn't matter. And I'm pretty sure Jason would agree with me on that, but feel free to ask him. -- Hanno Böck https://hboeck.de/
