If indeed both kinds of proxy are useful and direct proxies are more

implement a tool type NotificationProxy that is based on that API.
An interesting question I still haven't found a satisfying answer to
is: is the additional power of current proxies useful? and worth the
cost? Because the current freedom of proxies is the root cause of
invariant checks that even good proxy citizens have to pay.
One of the motivating use cases for Proxies is self-hosting exotic
built-ins and host objects such as current Web API objects. If the
standard built-in Proxy abstraction isn't expressive enough for that
job (and also efficient enough) then we haven't achieve the goal of
supporting that use case.
I agree, but I haven't read evidence on the thread that notification
proxies would have insufficient power to do so. In my other answer, I
pointed to a couple of expressiveness (minor) losses, but nothing that
would prevent self-hosting Web APIs. Do you have particular examples in
mind?
