Yeah I don't think this is possible, the `proto3` map is just syntactic sugar for: ```protobuf message map { string key = 1; string value = 2; } message ServiceConfig...

I don't believe it is. Are you interesting in implementing this?

Thanks for your interest! The thing I like to do first with something like this is to create a failing test. You can try adding an example like the one...

Is that not validating based on the OpenAPI 3 spec? Remember we only support OpenAPI 2 (swagger 2.0).

Looks mostly to be a problem with the way we're rendering the responses, could you dig a little deeper and see how we're violating the spec exactly?

This is being worked on in #671

How is your request different from that being implemented in #671? I apologize if I've misunderstood.

Good spot, this'll have to be a separate PR then. Sorry for the misunderstanding.

Be the change you want to see! What can I do to help you get this in?

The OpenAPI 3.0 spec has added support for [Authentication (JWT, Oath, HTTP Basic)](https://github.com/swagger-api/swagger-ui/pull/3780), which is something that is missing from 2.0. I think this would make it worthwhile to migrate...
