No you're not. I too enjoy working with text the completion LLMs have been able to do for some time. The issue with text completion is that most people don't want to be forced to think about possible document headers when they want inferred answers.
Another problem is that OpenAI doesn't want their customers to access them anymore. They may be considered too dangerous, since they are not just not instruction tuned, but also not censored (RLHF'd). So people have to use less powerful base models, which cancels out their increased flexibility.
