We're going round in circles now, so let's just say we will see what happens.

Project Zero seems upbeat, but acknowledges this risk:

> We understand that for some vendors without a downstream ecosystem, this policy may create unwelcome noise and attention

> This is a trial, and we will be closely monitoring its effects.

They don't explicity spell out what they would consider a failure of this policy trial. I think failure would look like the example I have outlined, but at greater scale.
