It's not technically possible with current service extension mechanism
to have a service, which can be used in both operating-system and
home-environment.  You can read more on possible improvements to
extension mechanism here:

However, currently it's just impossible without a huge (and probably
backward incompatible) refactoring of service extension mechanism and
perhaps all the services.

Even if it would be possible, still don't see too much cases, where the
system service is wanted to be used as home service and vice versa.
