When a vessel is packed, its OnFlyByWire callback is no longer active. It also means that physics does not fully apply, so we might get away by simply setting the ships position.
Vessel deletion regarding physics is a bit more complex: we should not force the game to keep the vessel active, but we should be able to respawn it packed (most likely) when the player comes within physics range of another players active vessel.
KSP uses at least two distance thresholds:
Keron should play nice with those thresholds.
