That's a bit of an exaggeration: the code would just look like in the
thousands of other cases where we are not sure whether the element to
delete is not at the head, like

  (setq my-list (delq elt my-list))

which is not worse, even better readable IMO, than a naked `delq'
call.

But I would be okay with that.
