There is another subthread in this conversation demanding that we allow
for exactly this.  I don't agree that it's useful, but I'm not
completely convinced that we can write them off just like that.

At the same time, if someone doesn't like what we are proposing here and
runs multiple session busses, I'm just flat out of luck with regards to
the guarantees that I want.

There's this certain "DBus is difficult for developers" urban myth
that's been floating around, and I'm not really sure that it's true. It
might be the case that having these two busses possibly be separate will
increase the confusion, but at the same type we're adding nice things
like GApplication that casual application authors can use without
exposing themselves to the details.
