Idea for the noise/bokeh effect
I like to put many point lights in the scene but that comes with a price of a noise dust even when rendering on 1500 samples. But what if we turn this into advantage?
So, I would like to turn noise dust into bokeh/blured circles. That is, every noise dust particle becomes center of bokeh circle.
Maybe additional node in the comepositor should be added to make this effect. Or maybe an option close to render button. This should separate noise from the rest of the image and then blur it with bokeh.

Anyway, if the problem is fireflies you can do your bokeh trick in the compositor with a "Greater than" math node to isolate pixels that are brighter than an arbitrary threshold
You mean: Render result -> Greater than -> bokeh blur-> ** add node** and the other is Render result -> ** add node** (the same add node as above) ?
How can Cycles tell what is noise and what not?
I don't know. Maybe there is a way.
