Signals don't need to be connected each time, you can just add a message filter
that match on interface + signal name, which has a one-off setup cost. This is
assuming that libdbus-glib lets you do this in a sane way, of course.

I think beauty, conveneince and performance are all good criteria for judging
an API. The difficulty is in achieving a good compromise.
