V-ray Light inconsistency on "visibility"

 I don't know why Vray lights are set to "visible" , or in some cases not set to "invisible" by default.   I can't think of any time I actually want my lights visible and to affect the alpha of the image.
    However.  no big deal,  I thought I'd write a little script to auto turn them off.. Only to discover that some lights use "visibility" and some use "invisible" for their channels. 

LightDome, sphere  and Rect Lights use "Invisible" while IES use "Visibility" 

In the end, I don't care what the channel name is.. but it sure would be nice if it was consistent.
