I am OK with adding this code or something similar. It is no more complex than
other places I have reviewed, eg `Item._init_link()`.

The issue is currently not easy to see and may be present in other places
without us knowing. I am also fine with a spec file check that highlights a
clash to draw attention to a problem when the spec files are parsed. I feeling
we need something.
