It's a bit before my time but I believe the initial sponsors were using
it. At least until development on it stopped.

The current state is not suitable for full-scale production use. Most of
the open bugs against 3.0 are ESI related and I think you should expect to
hit them for now.

It appears to be usable in small very particular situations so testing is
well worth it. A month ago we had one volunteer look into some of the
bugs. But there has been no word recently. I hope he is still chipping
away.

esi:include has several known problems. Some major. I would not be
surprised if that is another not yet mentioned in bugzilla.

I may be completely wrong but I would expect Cache-Control to work
normally on individual objects. In addition to Surrogate-Control.
