Repeating events or alarms may not involve any UI at all, but the device may need to trigger those at a specific local time - that means time zone information has to be taken into account somewhere. This is a crucial fact of any calendaring and scheduling system that those of us who have been using iCalendar (RFC5545) fully appreciate.

This is true, but any specific local time will always occur at a specific universal time, so this isn't actually a problem.
