it's definitely hard to follow this kind of reasoning: because we should all be using dice rolls to seed the RNG, let's make an oblique error message in an obscure part of the repo, to guard against a default operating mode that's catastrophic to users (who apparently received recommendations from Bitcoin Jesus II: The Revenge in "Mastering Bitcoin", an ironic title as it turns out). would an above-average reader of that book even understand the warning message?

why not simply remove ANY insecure mode whatsoever, seeing as the developer was so security conscious? it seems the answer is "demos"
