I note that Grandpa uses ed25519 keys rather than the substrate standard of sr25519.

Is it because sr25519 signatures are non-deterministic? ( Why are sr25519 signatures non-deterministic? ) or is there some other reason why ed was chosen over sr? Is there some inherrent reason why Grandpa can't work (or would be insecure) using sr25519 keys?
