This most definitely is just "we didn't bother checking the error too
carefully, especially because the result of deleting something that did
not exist in the first place is a no-op; anybody who tries to delete a
non-existing thing is a moron and deserves whatever random result he
gets".

It would be a good idea to tighten it.
