This was only done because the US assured the people in charge of
international aircraft navigation that they wouldn't turn it
off. (I'm sketchy on details since I was never able to track down a
primary source for this (supposed) fact.)

However, with navigation there is still the backup of intertial
systems. If accurate time is important to someone, they would
probably have a backup atomic clock. There's also WWVB and CHU for
those in North America.
