For the serious use cases you evidently have in mind, yes, it's folly to have it do double duty, but at the end of the day steganography is an obfuscation technique orthogonal to encryption, so the question of whether to use encryption or not is a nuanced one. Anyhow, I don't think it's fair to characterize this elaborate steganography tech as a poor-man's encryption — LLM tokens are expensive!
