It seems hypocritical. The TSA's long stated argument for having an SSSS system is, "We need to know more about you." Well, a trusted traveler program serves that very purpose. The occasional misfortune of a random is partially understandable, but Global Entry passengers should not routinely be subject to this.

I've had Global Entry for several years, and I've always had good luck (perhaps I've just jinxed that.)

I also used NEXUS for the fist time for travel by air, and did encounter secondary screening by customs, and I just got a web check-in Air Canada boarding card without the SSSS. I hope that the good luck continues.

I think that the variations of CAPPS need to be able to recognize a valid PASSID, and that would leave security agencies to concentrate their efforts on less trustred travelers. It seems like a pretty reasonable expectation.
