The problem with that is that the skipped data will still be present and therefore easy to recover if you know what you're looking for. That may "leak" seconds

The problem with that is that the skipped data will still be present and therefore easy to recover if you know what you're looking for. That may "leak" seconds worth of video (and audio) the user may have thought was removed. And those seconds may contain something sensitive, e.g. a pan over some confidential information on some paper or screen, or genitals, or whatever.
