       1. Supply chain risk. The greatest risk that JS should address. NPM reports that only 3% are only specific to the application and 97% are libraries.

+Jack Works - Provide an overview of the New Integrity Level
+
+Jordan - That makes sense why we wouldn’t want a protocol. If we had a protocol then we would have to verify that the users are using it correctly. There’s no way for an object to validate that my object is immutable. I think that almost every built in type should be inheritable.
+
+Mark Mill - I think the term immutable raises a bunch of issues here. Is there any invariant that you can stake across. Not useful unless you can

+Mathieu Hofman & Jack Work - There’s no standard for this.
+
+Jordan - The web will follow a similar pattern for it’s built-ins. We shouldn’t need 15 proposals.

+
+Jack - Would that cause problems with proxy
