I think I was not explaining my use case properly. It is not the Varnish cache I was talking about. The backend has it's own cache, and it can sometimes serve stale data (if requested seconds after an update). So completely removing the object from the _Varnish_ cache does not help here. And in fact it would just do harm, since if then the backend goes down we don't have any stale data from Varnish cache to serve. With softpurge and a long grace, we always are ready for a backend failure (assuming the data is in the cache).
