Most (all?) of the use cases for a package defining its own return codes can be achieved just as well by defining its own
-errorcode’s to [throw] and handling by the trap blocks inside a [try].

Errorcodes are better suited for avoiding naming conflicts because they already follow the convention of being list valued with the first element of the list being the owning package name.
