Autocomplete in GraphiQL shows properties for regions that are not in the schema of a particular region

[DigitalGoldfish]

This is due to the fact that all Regions are treated as being of the same type, which allows queries like "allRegions". But in reality each region is unique in it's structure and has it's own schema similar to a collection.
Personally I would prefer to create one type per region as it greatly helps when creating queries in GraphiQL.
