This is an active proposal at stage 3 of the TC39 proposal process. See: https://tc39.es/proposal-dynamic-code-brand-checks/ See: https://github.com/tc39/proposal-dynamic-code-brand-checks This proposal essentially adds support for the TrustedScript type from the Trusted Types specification to eval and Function. This in turn pipes support for the type into the CSP hook to check if the CSP allows dynamic code compilation. However, it currently doesn't support ShadowRealms, so the implementation here is a close approximation, using PerformEval as the basis. See: https://github.com/tc39/proposal-dynamic-code-brand-checks/issues/19 This is required to support the new function signature for the CSP hook, and will allow us to slot in Trusted Types support in the future.
