FWIW, we chose `offset` for `array_api_extra.create_diagonal`, instead of inheriting `k` from `np.diag`. `np.diagonal` and `np.linalg.trace` also use `offset`. Given that all of the proposed functions apart from `np.identity` already have "diag" as a substring of their name, I think just `offset` would be fine. What else could `offset` mean in the case of `np.identity`? I suppose there is an argument for actually leaving `np.identity` as is—if someone wants a square off-diagonal matrix of ones, which isn't an identity matrix, their code might be more readable with `np.diag(np.ones(...), k=1)` or just `np.eye` instead, right? Maybe it is weird for "eye" but not "identity" to have this capability, though.
