We only allow plain objects that can be faithfully serialized and deserialized through JSON to pass through the serialization boundary. It's a bit too expensive to do all the possible checks in production so we do most checks in DEV, so it's still possible to pass an object in production by mistake. This is currently exaggerated by frameworks because the logs on the server aren't visible enough. Even so, it's possible to do a mistake without testing it in DEV or just testing a conditional branch. That might have security implications if that object wasn't supposed to be passed. We can't rely on only checking if the prototype is `Object.prototype` because that wouldn't work with cross-realm objects which is unfortunate. However, if it isn't, we can check wether it has exactly one prototype on the chain which would catch the common error of passing a class instance.
react-client
This is an experimental package for consuming custom React streaming models.
Its API is not as stable as that of React, React Native, or React DOM, and does not follow the common versioning scheme.
Use it at your own risk.
