Are there some plans to land flow-type exports in v0.6.0?

[iamchenxin]

Without standard flow-type outputs in graphql's package.
Some packages dependent on graphql get more and more wrong flow-type check.(used wrong type but type-check passed in that package).

Ex: graphql-relay-js,It used a subset of graphql.
But cause there is no flow-type output in graphql's standard npm package, so graphql-relay-js can do type check arbitrarily, this will lend to some bugs.
Like graphql-relay-js :

type typeResolverFn = (object: any) => ?GraphQLObjectType |
                      (object: any) => ?Promise<GraphQLObjectType>; // wrong ? type can not be resolved with a Promise?

vs grapgql's

export type GraphQLTypeResolveFn = (
  value: mixed,
  context: mixed,
  info: GraphQLResolveInfo
) => ?GraphQLObjectType

And also if there are type-outputs in graphql
Something in graphql(L469):

export type GraphQLFieldResolveFn = (
  source: mixed,
  args: {[argName: string]: mixed}, // should be modified to args:Object or some template?
  context: mixed,
  info: GraphQLResolveInfo
) => mixed

would be narrowed rightly in graph-relay like this:

type RelayFieldResolveFn = (
   source: Object,
   args: {'input':Object},
   context: mixed,
   info: GraphQLResolveInfo
 ) => mixed
