[Bf-cycles] filter for out of focus samples

when rendering with cycles, I often struggle with the issue of needing too 
many samples when using strong DOF effect.
I thought, maybe for the out of focus samples could be somehow filtered/
blurred similar to what happens to glossy samples when they have filtering 
This would help probably best with the samples that are closer to camera 
that the focus plane, while I guess it could be easier to do it for these?

A nice example of the current problem can be the movie Whole by William 
While in this movie is the noisy defocus part of the visual style, I guess 
most users would like the possibility to get a smooth DOF effect...

I am also not sure if it is easy to detect the length of the ray with glossy
materials, so sorry if this is simply a bad idea ;)
