So the correct response per the AD is immediately hit the cut out switches.
Recall 3 FAA pilots simulated this & 1 failed, in real life things were not much different.
I would suggest you go back and re-read AD 2018-23-51 carefully (you can Goggle it). It does not call for the immediate use of the cutout switches. Of course there have been reports that this AD was not properly transmitted to the Ethiopian pilots, but even so using the yoke trim switches to keep the aircraft in trim is not exactly rocket science either.
As far as the test you refer to, it was a different malfunction than the one presented to the accident crews, particularly as it presented a runaway trim with the A/P engaged so no one was getting direct feedback through the controls. Even though the FAA reports that this malfunction has never been seen in actual operation, it deserves to be fixed because you never know when the stars will line up against you. The current FCC architecture relies very heavily on the pilots detecting a malfuntion, and if the airlines aren't going to properly train for this role then the architecture needs to be fixed.
