It should not impact physics.
Unless I’m misunderstanding this, it should not impact selection, since there’s already a Locked property. It should behave the exact same as a transparent part but for a whole PVInstance instead.
No, this can be checked with a quick if-statement before playing the audio.
No.
Edit: This is subjective, but I believe they shouldn’t be automatically set to invisible. Developers can manually disable them when they disable visible, but if they were to be automantically hidden then it would be impossible to enable them whatsoever while an object isn’t visible.
Yes.
This feature request is also similar to New property: Model.Visible.
