Generate structs for query / mutation / field args

[mikew]

Note: I am not a golang developer, so please excuse me if I use the wrong names.

We are migrating from an existing graphql server, written using @graphql-codegen. One of the things that does, is if we have things defined like

type Query {
  foo(name: String, sort: String): ...
}

type Mutation {
  foo(name: String, sort: String): ...
}

It generates interfaces rolling up those things together, ie:

interface QueryFooArgs {
  name?: string
  sort?: string
}

interface MutationFooArgs {
  name?: string
  sort?: string
}

But, I can see gqlgen just adds all the args to the generated query / mutation function:

func (r *mutationResolver) Foo(ctx context.Context, name string, sort string) (*data.Censored, error) {
   ...
}

Which just means diffs will grow and the function signature will change as new fields are added. Seems like if a struct was generated for the args, the signature would be stable and there would be less to review in diffs.
