It's easy to argue you are just rattling off buzzwords if you don't provide examples.
I would also argue that not based on a schema is even more brittle as you end up implementing validation logic and client marshalling that the schema would allow you to just generate.

Name some. Seriously, I'm interested in protocol design, so I'll read them. But also, yeah, just declaring that things exist is kind of unhelpful.
Such things exist, I'm not just rattling off buzzwords.
The main thing is protocols are serious business and people, especially any of the big five shouldn't get to own them just because it suits a business interest.
