nautilus is one of the few (in fact, the last on my system) components which spawn notification-daemon (or notify-osd) at startup, through querying server caps. nautilus uses the notification system only sparingly, during file copying progress reporting. It would be more efficient to lazily initialize the server cap query to only spawn the notification-daemon when necessary.

This improves boot speed a tad, by avoiding to start the notification service at all.

Thanks for considering!
