@Yoav @tomayac anyway, I don't know if the TaskAttribution API covers it or not... would be interested to walk through the use case.
I'm hoping it can be something simpler... like, for instance, being able to request more time for some particular actions within the context of an user activated event handler.
The key being that: "hey, I have permission to do some action here, so please grant me a bit more time"... and maybe that can be somehow attached to a callback or promise settling.
