To better understand my rant, a bit of context with the original patch
proposal (whose message is also contained in the commit I pointed to):
If you wonder why I react so late, this is because libvirt 3.0.0 landed
in Debian Stretch (Jessie had 1.2.9!), and I just recently upgraded to

Of course, as a workaround I can use "<link state='up'/>", but I think
it ought to be the default, hence my request.
