First of all: nice feature. I used "decorators" often and now they are an actual feature and I can prevent them from going into the schema! 👍

Is it actually possible to throw error at compile time, when I have:

SomeType:
  type: 'object'
  config:
    fields:
      someField: { type: 'SomeDecoratorType' }

While SomeDecoratorType is an object with config.decorator: true.

Currently an error is thrown when query is being executed.

Ok I get it, do you want to work on this?

I still have another thing I wanted to make, which you labeled 1.2, but to be honest with decorators and some other new features it almost got obsolete.

IN case of this one - please give me your thought on this - maybe the issue is resolved anyway, if you simply have a test that makes a full introspection query. This would trigger the error not at compile time, but test time.
