Given that the widgets don't have any actions defined and the routing is
all done by DT it might be easier and more flexible to just define all
the widgets all the time and let them hang there if they're not in use,
that way you don't need multiple compatible strings.  If you do that
you're then very close to being able to use simple-card...
