In general, I believe so, yes. To be clear, it only sets zeros into union padding, not *all* padding. I do not have an opinion on whether we want it to be `-fzero-union-padding` as opposed to `-finit-union-padding` that honors the pattern from `-ftrivial-auto-init=pattern` and defaults to zero if no pattern is specified.
