About the value this change, I think it should be same as the values at

Yup, I often do restart the services installed from ports, too. I meant
that I don't want that the values of user environment are inherited to the
services which is started from the user environment.
This is where the value of service(8) would lie for me. The ability to not
have things work by accident due to my environment and then break at reboot
would be be very helful.
There are several other types of context we've historically not properly
set/restored when managing service state, such as:
- Full user credential context (user IDs, group IDs, etc)
- Additional login class state, such as resource limits and MAC labels
- User audit state
With Apple's launchd, service descriptions can include user credentials that
will be set before the service is started. Being able to do that here as well
would be great, especially in a future where part of our supplemental user
credential will be additional system privileges.
