Questions:

• Do we want to make a new version of https://github.com/apollographql/specs/blob/main/kotlin_labs/v0.2/kotlin_labs-v0.2.graphql ?
• Is it ok that connectionFields applies to both standard connections and non-standard ones? The risk of name clash is probably low but still.

For those kinds of things that are iterating quickly and where tagging new versions of directives is cumbersome, what about a "draft" version like there is for the GraphQL spec?

I think it's ok to keep only connectionFields - with this change, we merge edges and nodes if present. So it's more like a extra thing that it does. If a nodes field is present and is not a list, it will be ignored, so I think it's not too risky.

I like the idea of having a draft version of the spec though - I can set this up.
