GraphQL union/interface ETA?

I’m planning a project that will be leveraging FaunaDB + GraphQL API (technology that has me VERY excited!), but find the lack of GraphQL union/interface support to be a major bummer as this particular project could benefit from these features in a huge way.

Just thought I’d ask if there’s any information that can be shared regarding the roadmap for these features, even if it’s not concrete. :grin:
