Fun fact: GPS uses 10 bits to store the week. That means it runs out... oh heck – April 6, 2019

Even better than adding 3 bits would be to take 3 bits away, because then it would roll over every 2.5 years and that's the sort of frequency that would force people to handle the roll-over properly, with tests, so a system that rolled over every 2.5 years would probably work for ever.

A device that had been stuck in a cupboard for a long time, or had a factory reset, would not be able to tell the user the date unless the user first told it the year. But it could still navigate without knowing the date. Adding bits is a stupid temporary fix compared to handling roll-overs properly.
