Just a difference in variable names owing to the different algorithmic origins.

It has the same underlying issues about reuse. The signature is a pure

It may be more prudent to just use ed25519 rather than apply its
technique for this issue— although you could— simply because the
ed25519 construct has had review as a whole.
