No, the proxy invariant checking mechanism never looks at inherited properties. Invariants related to frozenness (non-configurable, non-extensible) relate only to own properties. For example, even if an object is frozen, it may still inherit from a non-frozen object whose interface may change. And then there's `setPrototypeOf`, which may cause inherited properties to change altogether.
