I find that highly unlikely; if you look at the code, we don't do any kind of manipulation of the keys, we take the keyword from the :resolve of the field, and use it as a key into the map of resolvers (or resolver factories).

That is what I thought. I'll keep looking. It is probably something I'm doing wrong.

I recently found some additional specification about subscriptions, but I'm not sure about the status. It seems limited implemented by GraphQL servers. https://github.com/apollographql/subscriptions-transport-ws/blob/master/PROTOCOL.md
