Now that is a question I think others could answer (tollef, sky,
phk?). I really do not know.
I agree that this could be interesting for, say, really big files
cache re-validation, without all the transfer from the backend to
Varnish, and even worth if we are talking about using Varnish for CDN
architectures (for better geolocation when delivering, with distant
backends, in many cases over continents).
Needless to say, this could be valid and very useful.
