As I understand it, area lights use an algorithm more like adaptive 
antialiasing than focal blur.

The sampling parameters were probably originally intended to be set in 
the scene file, this is probably just an oversight, something never 
completed(like "track" in light sources, and "type" in black hole 
warps). More sampling methods/parameters definitely would be useful.
