Script for blurry reflections ?

I was doing a search on this site when I found this thread

https://blenderartists.org/forum/viewtopic.php?t=57936&highlight=blurry+reflections

It seems to me adding an extra slider in the shaders menu for blurry reflections seems like something pretty trivial to code. Since the workaround works like a charm, I wonder if there’s anyone would like to volenteer to write a simple script which adds this option ?

Thanks !

the yafray/blender intergration has been halted, there is a planed re-write of yafray, though it is not going so fast atm, both the main coders are very busy atm

also the integration for yafray is being re-writen and cleaned up, i have no idea whats going on with that though
