It counts as a weird feature.  At first, I thought it was just a "no damage
by default" setting, but I recently read somewhere (sorry, completely
forgotten where) that the idea behind network-dummy is that, since Debian
has the ability to configure all your bridges at boot time, that you should
be using that instead of the Xen network config scripts.
