With Vintage Air systems, are you guys running an RPM cutoff switch?

I am using the Sanden compressor in Holley's midmount accessory drive system and i know a lot mention an rpm cutoff switch. There is even a paper in the compressor box talking about it. The compressor in the Holley kit is the SD7B10. I am just curious though because when you go off the Sanden service guide data, it specifically states that that specific compressor is rated at 6500 constant rpm's and a spike of 9300. Just seems like nothing external should be needed given that data.
