> you won't get very far without them

In the workplace, I think the opposite is true. Understanding and treating coworkers as individuals gets one much further than this sort of incredibly granular categorization. You're bound to miss important things about people if you just think of them as a "disagreeable taker" here or an "agreeable giver" there. Most importantly, you'll miss that people not only fluctuate in personality day to day based on many factors, but indeed often change entirely over time. It's not that this kind of mumbo jumbo is "unfashionable", it's that it isn't useful.
