He can only do so much, he can't think and can't include every possible detail. I disagree. Kishimoto introduced the Shin in the canonical timeframe months or weeks before the exams. As you mentioned, there was no time for greater reinforcements. Plus, Boruto only got to tag along because Sasuke decided to. I don't see why kids like the Shin would be allowed to go.

So no, there are proper and legitimate reasons they didn't go, as the writer intended.
