Micheus,In my environment, even if set the background-color to rgbt, I could't get transparent background.
So I added pigment options both "filter all 1.0" and "transmit all 1.0",Then background transparent is works.
(I edited a pov file as following )
I don't have a deep understanding about the options...
Could you try filter and transmit option to the caustics problem?

Do you have any plan enable set the rendering quality?
In the GUI version of PovRay has a pull-down menu for rendering quality.
This feature is easy for user to understand .
