No, it's required esp. for `in_bounds` = `false` since we use the pad value to fill the out-of-bounds elements. I think the `in_bounds` attribute became obsolete with the introduction of masking. It is actually a scalar implementation of it which should be redundant at this point but... we are still generating it :)
