Whatever you do, if it warrants the use of something like `handle_atom_del`, chances are `Exited` can do it better, as most of these cases involve movables that shouldn't be moved out of their loc (`Destroy` forcefully moves movables to nullspace) without calling specific procs, and for the remaining few, `handle_atom_del` doesn't even cover the eventuality of a movable being deleted outside the source atom, so it's quite garbage. Beside, I feel confident in saying `handle_atom_del()` is older than the DCS, an echo on the workarounds done at the time.
