Importance sampling for DoF and MB

The big cool feature of Corona is fast DoF and MB. But with very bright spots sampling of this effects is unacceptable. Is there any chance to see IS integrated in this effects?

upd.: (or may be another sampler like QMC if therу is simple random sampler)
upd.2: (or may be some kind of adaptivity in another way)
