Laughter in a recording is not transcribed, and shows up as "silence."
Thus bulk remove of silence removes laughter, and other non-word communication (gasps, sighs, etc.).
Ideally transcription would tag common exclamations as Laughter, Sigh, etc.
Barring that, it would be nice if it could distinguish between actual silence, and non-word sounds in transcription so that shorten silences wouldn't cut out things like that, or could be at least be configured not to.
It seems like the "tagging" functionality would be a good match for this, however that does not work on Multitrack, and this feature would be needed in Multitrack as well.
