Well, any proper bench power supply should be able to handle any kind of load without killing itself, including highly capacitive/inductive ones, fast/wildly changing ones and indefinite short circuit.
"Proper"
"Should"
Good luck with that.
When I first encountered "active loads", I thought "Great! Now we can synthesize complex loads to automate testing of supplies."
Turns out they typically do constant resistance, constant current, couple things like that. And often go unstable with some of those options.
Hardwired test loads are a way to test some points in the complex plane.
How many off-brand off-shore no-name suppliers do any of that?
Now feed a switching power supply into a switching power supply and see what happens.
I have a stack of linear boat-anchors at ballast at the bottom of my test equipment rack.
The Keysight 40W, four-output 6624A is a versatile solution to help improve system accuracy and reduce test time in a 3U high package.

In a custom switching power supply board design (10 outputs of various voltage and current, buck, boost, inverting), we had some that would spontaneously die. Only a percentage of them. I tried to test out some theories, stressing a control unit and one I modified, but couldn't kill either. Maybe it was 10% infant mortality of the IC at a particular stress level. Same component and circuit topology for a 17V and a 10V supply, and only the 17V one ever failed (several times at that.) All within data sheet specs.
