The way I read it, the new spelling lof that would be the explicit but not discouraged `image.vindex[rr, cc]`. > I would reserve warnings for the cases where the current behavior is something no one really wants, like mixing slices and integer arrays. These are the cases that would only be available under `legacy_index`.

It should not issue warnings or (eventual) errors.
