This does not change the default behaviour, and happens in an LTS
release, so I'm inclined to agree to this.

This seems fine.

I don't really see how this is related to the ability to define which
indicators to load? AFAICS these are really two independent changes,
and thus should be in two separate patches? This second one does
change the default behaviour (the indicator now creating a new D-BUS
connection and exporting an object), so this needs careful testing.
