> think most people who use JSON don't want strong typing or to use schemas. If you do, you just use a different serialization format: JSON is designed to be a generic, human-readable way to basically represent any kind of data structure (since it deserializes to JS objects). So everything about JSON is working against you if you do try to enforce type/schemas on it.

I have been using serde without issues, and never resorted to `serde::Value`[0], the untyped option, so far.

I have yet to experience anything working against me.

I definitely want jsonschema, it's a standard and i can use it for many tools. openapi spec is also a standard and built on top of jsonschema. I can use jsonschema to generate models, types, servers, client sdks, automate forms etc. I think it's better than grpc for some of these things, plus protobufs and grpc have bunch of tooling that i can pretend to understand but in depth i don't really.

We use JSON because it's standard, human-readable, mostly self-described and works natively with Javascript.

You can read JSON object without having to know the schema even if one exists.

Protobuf is unusablr garbage without a lot of supporting tooling.

Not necessarily. It's biggest advantage is probably that it has very good interoperability. Basically every language has a readily accessible library for json, and even if you don't, it isn't that hard to write a parser and/or generator for it. And being human readable isn't something to sneeze at either.
