I see that while the common notifiers code uses this class - and Nova
uses the common notifiers code - Nova itself doesn't use the class. So,
I'm not sure how this is supposed to work.

I haven't looked too closely, but I suspect you're correct. The Context
class is one of the parts of openstack-common which I think needs more
work for it to be generally useful across projects.

My one concern is that we may make this class so generic that it
actually contains very little and isn't very useful to have in
openstack-common at all.
