[web2py] smartgrid breadcrums not displaying Id when details=False

[wwwgong]

found from sqlhtml.py that smartgrid breadcrums displays Row Id only if 
details=True:

                   if kwargs.get('details', True):
                        breadcrumbs.append(
                            LI(A(name, _class=trap_class(),
                                 _href=url(args=['view', referee, id])),
                               SPAN(divider, _class='divider'),
                               _class='w2p_grid_breadcrumb_elem'))

This is not obvious to me, Can someone shed light on this logic?
Thanks,
W
