I'm trying to remember. Perhaps it stemmed from the side consequence of
needing to know if a particular service had a socket entry, and therefore
you needed to disable both to disable a service? (I do recall there being
issues with socket-activated NetworkManager for reasons along these
lines.)

For something like cups, would this impose a significant delay in things
such as the GTK or QT print dialog, if opening that dialog causes the
cups daemon to then start?
