Sorry if I jump into the discussion sideways - I am not really part
of the glue group, just lurking here.

Anyway: yes, you certainly can have services w/o endpoints, or at
least which have no need to expose an endpoint.  For example, we
have a garbage collection service which at specific intervals scans
our data bases and purges expired entries.  That service is never
contacted from client side, and nobody really cares where it runs
(apart from the deployment point of view of course).

And yes, that service could very well specify quality levels, such
as run frequency.

Not sure if that is relevant to the discussion, just wanted to throw
that in ;-)

Best, Andre.
