True. However, there are "memory items" that have to be done from memory when the situation does not allow time for a checklist. Stall recovery is one of them, which is exactly when the MCAS is supposed to activate. I'm pretty sure runaway trim is another since it won't take long to end up in a very bad attitude if this happens, especially at high airspeeds.
There’s just not much time as often cited as the problem when a pilot makes a mistake in a stressful situation, so seems like the add more training mantra ignores a more fundamental issue.
