There’s a huge difference between “the famine never happened” and “The widespread crop failures caused famines in some regions due to ineffective policies, bad estimates grain production, and local conflict”.

The former is just as wildly ahistorical as the “Stalin did holodomer because he was evil” that’s taught in schools.

While that might work for someone whose only interest in the event is demonizing (or eulogizing) the USSR, if you actually want to know how and why things happened, a deeper understanding is necessary.
