Comment (by nomeata):

 >  But I don't feel strongly. A Note at least?

 Me neither. Direct is nice, less code is nice. I’ll add a note, and not
 set the call arity annotation.

 (Although it is debatable whether the simplifier is really innocent. The
 annotation is *true* even on join points; it is the simplifier that is
 stubbornly (but with good reason) refusing to eta-expand the join point!)
