You bet this will be covered in future B737 recurrent training curriculums along with a demonstration on non-recovery compliance with MCAS, probably in both high and low speed regimes.

Unfortunately it seems like the ET pilots got themselves in a tough position with the multiple MCAS trim inputs without disconnecting electric trim and/or providing proper runaway trim recovery techniques.

The situation compounded due to an extreme high speed/thrust setting. Either A) Auto-throttles were never disconnected (per procedure) or B) Airplane captured altitude hold setting keeping the current airspeed/thrust position and pilots never reduced to a manageable speed.

At a slower airspeed, manual trim movements are easier to conduct and the negative aerodynamic effects of the out of trim situation are significantly reduced. Flying fast with takeoff or climb thrust still active and trying to handle a flight control issue, that’s a really difficult position to recover from.
