Absurd for three reasons:

- You've produced no evidence these pilots are at any training limit, you just made that up, so I call bullshit.

- I'm a pilot and a former flight instructor so I have some credibility in refusing a binary choice like you've proposed. It's not that much training. I had to do difference training for checkouts on a regular basis (giving it and receiving it) and it's not high quantity training, it is high quality training.

- The strongest argument there's plenty of opportunity for training is the fact the MAX had the same type certification as the previous NG model series. So what's the worst case scenario for difference training? It'd require an aircraft type certificate, which will require pilots undergo training and checkout for an additional type rating.

Quite a lot of pilots have multiple type ratings, it's not unusual, in fact the pilot of Ethiopian Airlines 302 had type ratings for B737-7/800, B757/767, B777, and B787. What, was he only training and never flying?

A fourth reason:

Wouldn't a pilot rather spend some time to train for a new potential issue than not know what to do when that issue came up?
