I mean, I'm referring to things I've had to deal with. Failure isn't obvious until the user complains of random disconnects, and then you find that although everything looks fine from the outside, you can wiggle the wafer inside like a loose tooth. The plastic of the wafer has cracked and is being held in place only by the metal in the contacts. I'll grant that it's robust in that it continues to work more than I'd expect, for example continuing to charge the laptop but not reliable for the external display. And once connected, sure it's secure. I suspect it's not the cable mating that causes the failure, but other foreign objects… keys in the bag or something… that manage to dislodge it. And some laptops have more play in the connector than others, which I think allows the connector on the cable end to hit the wafer with an angle of attack sufficient to dislodge it. Some of my users handle heavy bulk materials all day and are anything but gentle with computers. In any case, I'm sure the designers considered this, and far be it from me to second-guess their compromises. It is what it is. But if the port has failure modes, this is one of them.
