Oh good call to check this here - but I'm not sure we want to assert the whole schema is valid before extending it, we want to preserve the use case where you can extend an incomplete schema to get to a complete one.
I have an idea to extract just this check out, one sec while I test it out

Introduces new predicate and assertion functions for each kind of type mirroring the existing ones for the higher order types. It also includes predicates for directives and schema. This should remove the need to use `instanceof` in any usage of GraphQL.js This consolidates the checking of instances which generalizes the cross-realm/multiple-module check so that the clearer error message is provided in nearly all scenarios, reducing confusion. This also replaces nearly all `instanceof` with new predicate functions internally. Fixes #1134

Checks if schema is valid with the
assertValidSchemahelper instead of a simple instanceof check. This gives the developer actionable error messages when there are multiple versions of graphql in node_modules.
