Does the actual value written matter here?
If so, it'd make sense to define a constant (or bit definitions in the rnndb).
If not it's fine like this, or add a comment that it's just a "random" nonce.

Is it intentional that this defines the same fields three times?
Why not return the same structure for all three cases? Is this expected to
change to
specific implementations soon in another patch?
