I agree that Noah has a reasonably good point here. I don't think it's
a total slam-dunk but it it's certainly not a stupid argument.
Conceding that point for the purposes of discussion, I don't
understand how this kind of proposal gets us out from under the
problem. Surely, it can't be the case that user X can cause event
trigger E to run as user Y unless X can become Y, because to do so
would allow X to usurp Y's privileges, except in the corner case where
Y never does anything that can trigger an event trigger. But if X has
to be able to become Y in order to force E to be run by Y, then I
think we've made no progress in addressing Noah's complaint.
