I don't think they have to remember all of them. Pilots rely heavily on checklists to make sure procedures are followed correctly and few mistakes are made.

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.

When US Airways Flight 1549 lost both engines, Captain Chesley "Sully" Sullenberger intentionally skipped some items on that checklist. The checklist had been written with the assumption of higher altitude and he didn't have enough time to go through everything.
