Since we are using circe-derivation only for this single (and simple) type, how about deriving it manually and only depend on circe-core?
Because not everyone uses circe-derivation, some people use circe-generic, others circe-magnolia. That way we would keep the dependency minimal.

I think codecs created by circe-derivation macros depend on the circe core only, so people won't need circe-derivation as a dependency. Although, to be on the safe side I can indeed implement it manually.

Oh yeah, you must be right! All good then.

If we reduce the dependency to circe-core as I suggested in the other comment, this is good. But otherwise, I think we should keep that one so that people who use caliban-http4s don't need to add the dependency to circe-derivation themselves.
Circe codecs for
GraphQLRequestandGraphQLResponseare generally useful, so I moved them out of the http4s integration module. I also madeGraphQLRequestpublic.The pull request uses the trick described in https://blog.7mind.io/no-more-orphans.html — circe dependency is marked as optional, so you don't need circe to use caliban, but if you have it, the typeclass instances will be available without additional imports.
