Fair enough. Though, a reorg at an early height doesn’t have to be problematic. It could normally happen, intentionally or accidentally. For example, if you yourself, or someone else fed blocks via submitblock or directly without announcement over P2P. I know that the new PoW DoS protection in headers-first download likely protects against a low-work reorg during IBD over P2P, but I don’t think it does over RPC.
