I certainly understand why SE limits it if it requires a GM's manual action to restore the items. Otherwise they'd be constantly getting flooded with tickets to handle, taking GM time away from more important issues that they need to handle.

Like Liam, I wish they would implement something similar to WoW's automated item restoration where you were allowed opportunities at certain time interval to restore a limited number of items. It would require you knowing what you had gotten in exchange for the item so it could be removed from your inventory when the item was restored or the restoration would fail. Such a service wouldn't harm the game in any way, nor take up GM time.
