Group owner's objects should be exempt from being returned

I really wish that owners of groups could have their objects that are set to group be protected from accidental returning by members who have the ability to return group objects. Group members tend to leave trash laying around so it is necessary for certain members to be able to return those objects, but mishaps such as misclicking or lagging out can lead to other objects being returned.

I should be able to trust group members with that ability while having peace of mind that my objects are safe from accidentally being returned.

It would also be nice if SL did not return objects set to the group when someone drives a vehicle on to the land and puts it over the prim limit.

The closest thing I have found is to lock the objects, but even locked objects can be returned.
