Empty hostgroups work just fine. The check that says this is so starts
at line 12516 in xdata/xodtemplate.c as of latest CVS/git. It's been
like that for a while now.

So what you *really* want is some way of assigning services to hosts
from within the service. That's an entirely different thing. You could
add "register 0" to the fake host definition. Not sure if that would
work, but it's possible that it does.

The hopefully-up-and-coming way of handling this is to use service sets,
a feature I've been thinking of for quite some time now. It can be
safely implemented without altering the object structure version, which
is quite nice, and will mean you can assign a set of services to a host
from within the definition of that host. The idea is to, in the long
run, use service sets to create full host types that can be shared among
community members.

Would that satisfy your needs?

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
