Interface resolveType is not optional

It should be possible to define:

export const UserError = interfaceType({
  definition(t) {
    t.string('id')
  },
  name: 'UserError',
})

But I get an error:

Argument of type '{ definition(t: InterfaceDefinitionBlock<"UserError">): void; name: "UserError"; }' is not assignable to parameter of type 'NexusInterfaceTypeConfig<"UserError">'.
  Property 'resolveType' is missing in type '{ definition(t: InterfaceDefinitionBlock<"UserError">): void; name: "UserError"; }' but required in type '{ resolveType: AbstractTypeResolver<"UserError">; }'

Well, I seem to have found it pretty quickly after all. Adding this to the config object of makeSchema()

features: {
      abstractTypeStrategies: {
        resolveType: false
      }     
    }

I’m getting this error now and wondering what the correct fix for it is. Does anyone have one?
