As for my usecases; on previous versions of SFOS it happened to me about once a week that I lost GPS lock completely, and just about nothing except reboot fixed that. No help recycling connectivity, restarting lipstick or killing positioning related daemons could fix it.

Since updating to 3.0.0.8 the bug has not manifested again, GPS snaps to lock almost immediately and there are no known hickups requiring reboot.
Currently uptime is 19 days and counting. It looks like I'm going to go to the next version update before I need to boot my device
