What "hasn't happened yet" is that any tax due is not reportable or payable until 2025. But the liability started on 1 January 2024. Many people listening to the "don't panic" head-in-the-sands mob, will not understand this. They could still make right or wrong decisions that affect their liability, if they don't know about it.
